The spread and development of the Indus Valley Civilisation, also known as the Harappan civilisation, one of the oldest civilisations of the world, is still an enigma. Indus Valley Civilisation was spread over modern day India and Pakistan. The civilisation has been divided into three phases, Early or Pre-Harappan, Mature or Urban Harappan and Post- or Late Harappan. The Urban phase is very well studied and understood. However, this phase is the culmination of a process that started much earlier. A lot of effort during recent years has led to new discoveries and clues regarding the interactions during the Early Harappan period between now politically divided areas. Unfortunately, this struggle to understand the spread of Early Harappan cultural traits between these distinct regions is one on-going and far from over. Explorations and subsequent excavations at the site of Juna Khatiya, situated in Kachchh district of Gujarat, India have brought to light noteworthy evidence of the Early Harappan period in terms of artefacts and burials. Other than the ubiquitous pottery, these indications include a lithic blade industry comprising of various types of blades, various types of scrapers, points and associated lithic debitage. The tools are made out of locally available raw material (mostly chalcedony). However, the discovery of a few blades of chert imported from the Rohri hills (situated about 500 km as-the-crow-flies from Gujarat) in modern Pakistan is important. Rohri chert blades are significant since they are very distinct and easily identifiable. The wide distribution of standardised Rohri chert blades is also often regarded as a testimony to the Harappan efficiency in long distance trade and craft production. The technique used in the manufacturing of these blades is known as the crested guiding ridge, a technique not observed in Gujarat before this contact between Sindh (in modern Pakistan) and Gujarat (in modern India) developed. This paper highlights the contributions of lithic artefacts to understand the Early Harappan interactions between these two politically divided but culturally united regions.

The Rompecráneo is a special kind of lithic artifact which was, presumably, involved in the capture of pinnipeds carried out along the Patagonian coast of Argentina during prehistoric times. Recent papers had offered some information about their morphology but up to now they are poorly studied. In order to offset this situation in a previous work we addressed their role in hunting technics developed at the archaeological locality of Punta Entrada (Santa Cruz, Argentina). This allowed us to propose that rompecráneos were used in combination with spears when hunting on the coast. With the aim of expanding this information, here we present an image gallery of some rompecráneos recovered there. Two of these pieces share a similar morphology but were made of different lithic raw materials. The other one has the appearance of a bola stone but its weight is higher than other bola stones in Patagonia. That is why it is considered a different kind of artifact. The importance of studying these kinds of artifacts is that they have the potential of providing information about the way people interacted with the different resources (biotic and abiotic) in the past so that a better understanding of human behavior can be developed.

In order to find out about and discuss the peopling of the Americas, there is evidence that comes from a range of scientific disciplines. In archaeology, stone tool vestiges are one of the main pieces of evidence used for assessing the knowledge and understanding of this topic. One of the most iconic lithic remains from the South American Paleoindian record is the so-called Fishtail, or just "Fell" projectile point, a distinctive artifact that stands out due to its wide distribution from southern Mexico to southernmost South America. Different hypotheses have been proposed regarding its origin, mainly related to Paleoindian points from North America. In order to discuss this issue, special attention has been paid among the existing varieties to a group distributed throughout eastern North America, mainly in states with a shoreline on the Gulf of Mexico. This group stands out, because with their narrow or broader blades, their lower portions typically have deeply indented concave edges, forming flaring rounded or pointed ears with fluted and unfluted bases which are reminiscent of the Fishtail. By comparing them from a morphological and technological viewpoint, and because of the observed similarities between North and South American fishtailed points, the hypothesis in this paper proposes that South American Fell points are related to similar ones from eastern North America. A model of the possible route/s followed by the waves of colonizers who peopled northern South America and the lands beyond the equator in the southern hemisphere is also proposed.

Yup'ik women have traditionally formed one half of a partnership with men in Southwest Alaska, through which one could not only survive but thrive in the Subarctic environment. Consideration has been given to identification and analysis of socio-technological attributes associated with the male sphere, often with regards to the qasgiq, or men's house, but less attention has been paid to the role of the ena, or women's house, counterpart as a space for women. The ena once provided a central space for women to transform wild catches into both food and supplies, vital activities that Yup'ik women still perform today. The analysis of lithic tool use-wear, especially that of unmodified flakes, and debitage in a 1,500-year-old Norton tradition house identify this space as the domain of women when evaluated against ethnographic examples of Yup'ik households.

Archaeological research has been carried out in the Eastern Rif (Morocco) since 1995 by a collaborative Moroccan-German research team. A major topic of the project is the transition from hunting-gathering to food production and related cultural developments. Innovations such as pottery and domesticated species appeared around 7.6 ka calBP. The cultivation of cereals and pulses is evident at that time. Two of the most important sites in the area are Ifri Oudadane and Ifri n'Etsedda. Both provide Epipaleolithic as well as Neolithic deposits. While innovative technologies such as pottery production and cultivation indicate external influences, lithic artifacts demonstrate local technological and behavioral traditions. Therefore, the study of lithic industries is crucial to understanding the nature of cultural continuity and discontinuity between the hunting-gathering and agricultural populations in the Eastern Rif. Ifri n'Etsedda provides two distinct Epipaleolithic deposits and thus offers the opportunity to study possible changes throughout the Epipalaeolithic and relationship to the later Early Neolithic (ENC). In combination with the earlier phases of Early Neolithic assemblages (ENA, ENB) at Ifri Oudadane, we are now in a better position to understand the development of early-to-mid Holocene lithic technology in the Eastern Rif. We show that the lithic record of Ifri n'Etsedda does not indicate any significant change in raw material supply, blank production, and tool distribution from the Early Epipaleolithic to the Early Neolithic B. Therefore, we argue for behavioral continuity from the Epipaleolithic to the Neolithic period. In contrast, the assemblages of the Early Neolithic C show changes in lithic technology.

Vorganjska peć is an important prehistoric cave site located on the slope of Organ hill above Batomalj near Baška on the island of Krk. The research of this site, as well as other cave sites on Kvarner islands, was initiated by Vladimir Mirosavljević in the mid-twentieth century. As the result of his research, Vorganjska peć, alongside Jami na Sredi on the island of Cres and Vela špilja on the island of Lošinj, became a significant source of data about the Neolithic of the Kvarner region and thereby an essential part of discussions about this period on the eastern Adriatic coast. Since this research was never fully published, the site was re-excavated in order to review previously obtained data about the cave usage in prehistory. The research results provided insight into the stratigraphic sequence of intact prehistoric archaeological deposits with Early and Middle Neolithic finds. The analysis of stratification and artefacts contributes to our knowledge of complex mechanisms of neolithisation of the eastern Adriatic and confirms the undeniable informative and interpretative significance of the site in the studies of the northern Adriatic Neolithic.

The knowledge about rocks availability in areas of archaeological investigations is fundamental in order to approach the lithic technology studies and human behaviors associated to its production. The aim of this paper is to characterize the structure of the basis of lithic resources of the area and to contrast previous observations. Here we present the first results of the prospections carried out in an inactive littoral cordon at the archaeological locality of Punta Entrada (Santa Cruz river mouth, Santa Cruz). Also petrographic analysis of samples recovered there are exposed. Patagonian Shingle Formation is the only one with outcrops in the area. This Formation would have functioned as a secondary source of a wide variety of lithologies of different qualities, which are presented in different sizes and morphologies thus offering a wide range of possibilities to the knappers.

Human populations used different lithic tools in order to address daily activities in everyday social reproduction. One way of approaching these instruments is by studying how lithic edges, points and surfaces were formatted. In this work, we are interested in introducing tool manufacturing by human populations that inhabited El Alto-Ancasti mountains (Catamarca, Argentina) during the first millennium of the era. For this purpose, we evaluate technical, morphological and functional characteristics of lithic instruments retrieved from excavations in different sites of eastern Catamarca, and then analyze the differences among the latter. In addition, this work is a contribution to the study of instruments made of quartz, a raw material that displays particular features in terms of hardness and quality for knapping. It also practically represents the whole lithic technology found in archaeological sites in a wide area of central and northern Argentina. [ABSTRACT FROM AUTHOR]

Fuente Mudarra is on a gentle slope on the left bank of the Pico River, near Sierra de Atapuerca, Burgos, Spain. A 12−m2 test pit was dug at this large open-air site between 2012 and 2017. Several upper Pleistocene archaeological levels were documented. Results from Fuente Mudarra confirm that Neanderthal groups, little represented at cave sites, occupied Sierra de Atapuerca from the end of the middle Pleistocene and during the upper Pleistocene. The site also provides insight into Neanderthal spatial organization in the Atapuerca area and whether they used the caves in an occasional, non-habitual way like the open-air sites.

The Côte Chalonnaise (Saône-et-Loire, France) is a region rich in Palaeolithic sites. The Magdalenian, however, is underrepresented in the region when compared to other periods. Recent research at the site of Grotte des Teux-Blancs provides new insights into the Palaeolithic occupation of the site and proves its use during the Magdalenian. Since the first excavation in 1913, the site has received little attention from researchers. To reconstruct the site’s occupation history, excavations were carried out in the back-dirt in addition to a new analysis of the known inventories. These excavations were able to provide insights into the 1913 excavation methods as the excavated sediments were deposited on the back-dirt separated by layers, forming an inverse stratigraphy. The analysis of the finds shows a small Middle Palaeolithic and a larger Upper Palaeolithic assemblage. In particular, the lithic and organic artefacts attest to the use of the site, in a hunting context, during the Magdalenian. The embedding of the site in the Magdalenian of Eastern France suggests that Grotte des Teux-Blancs, together with other sites west of the Bresse, was part of the same settlement system as the sites of the French Jura.

The Patagonian coast has been occupied at least since the Middle Holocene but the way in which humans have interacted with spaces and resources in different areas of the coast has varied. As such, it is important to study the specifics of each occupation. In this paper, the activities that would have taken place at Cabeza de León 1 archaeological site, Monte León National Park, Santa Cruz province, Argentina, are addressed from the study of the recovered lithic assemblages. Results show the use of local raw material, the development of all manufacture stages in situ and the implementation of mainly expedient strategies. It can also be inferred that activities were mostly related to the capture and processing of resources. La costa patagónica ha sido ocupada desde mínimamente el Holoceno medio, pero el modo en que los humanos interactuaron con el espacio y los recursos a lo largo del tiempo en los distintos sectores fue diferente, lo que hace necesario estudiar las particularidades de cada ocupación. Aquí se abordan las actividades tecnológicas que se habrían desarrollado en el sitio Cabeza de León 1, sito en el Parque Nacional Monte León (Santa Cruz, Argentina), a partir del estudio de los materiales líticos allí recuperados. Estos muestran el empleo mayoritario de materias primas locales, la realización de todas las etapas de manufactura in situ, la implementación de estrategias tecnológicas principalmente expeditivas, y también permiten inferir actividades mayoritariamente vinculadas a la captura y procesamiento de recursos.

The distances that prehistoric hunter-gatherers transported lithic artifacts are often used to estimate how far groups moved across the landscape. Changes in the scales of stone tool transport, likewise, are frequently attributed to changes in group mobility behaviors. It is unclear what effects, if any, technological changes related to the design, manufacture, use, and discard of stone tools would have had on the broad archaeological patterns of stone tool transport that we use to make inferences about group mobility. This paper uses an agent-based model to explore how these humanlevel behaviors affect the accuracy with which transport distances reflect the scale of group residential mobility. The world of the model represents a simple "tethered" system where patterns of seasonal group movement are centered on aggregation at a lithic source. It includes representations of group-level mobility as well as parameters controlling three basic components that affect the utility of a tool kit: use-life (how many times a tool can be used before it is exhausted), inventory size (how many tools are carried), and frequency of use (how often tools are used over a given period of time). It also includes parameterized representations of "gearing up" behaviors that affect the number of new tools produced at a lithic source. Systematic experimentation demonstrates that these behaviors in combination have significant, patterned, nonlinear effects on the maximum distances with which stone tools are transported from their locations of manufacture. In a large number of cases, the maximum distance which tools are transported prior to discard significantly underestimates the maximum scale of group mobility. Many different combinations of tool production, use, and discard behaviors produce similar outcomes with regard to the scale of tool transport, suggesting that equifinality problems should be addressed as part of any consideration of changes in stone tool transport patterns.

A methodology for identifying prehistoric local learning communities is proposed. We wish to test possible relationships among communities based on continuity and variability in lithic reduction sequence technological traits with different visibility and malleability. Quantitative features reflecting different technological traits are measured on 3-D models of flint cores in different scales: the ratio between core thickness and reduction surface width, the angle between subsequent bands of production blank scars to the relative striking platform, and the average curvature of the ridge between each blank scar striking platform pair. Continuity and variability in these features are used to establish the relations among lithic assemblages on different hierarchical levels: local learning communities and geographically widespread cultural lineages. The Late Upper Palaeolithic and the Epipalaeolithic of the Southern Levant (ca. 27,000-15,000 cal BP) provide an opportunity to test our method. A progressive increase in territoriality is hypothesized throughout this timespan, yet the precise timing and modes of this phenomenon need to be defined. The present study analyzes six core assemblages attributed to different cultural entities, representing chronologically separated occupations of the Ein Gev area and the coastal Sharon Plain. Continuity in technological traits between the Atlitian (ca. 27,000-26,000 cal BP) and Nizzanan (ca. 20,000-18,500 cal BP) occupations of the Ein Gev area suggests that the same learning community repeatedly settled there during a long time span. Two geographically separate learning communities were defined in the study areas within the Kebaran cultural entity (ca. 24,000-18,000 cal BP); the group occupying the Ein Gev area possibly continued to settle there during the Geometric Kebaran (ca. 18,000-15,000 cal BP). Continuity in more conservative traits of the reduction sequence allows to tie these two communities to the same cultural lineage. The ability to track prehistoric learning communities based on quantitative features helps increase the objectivity and the resolution in the reconstruction of past cultural dynamics.

Mesolithic pioneers reached Gotland around 9200 cal BP and adopted seal-hunting. The subsistence economy was flexible, and the importance of freshwater fish is reflected in the location of settlements and available stable isotope data. Overgrowing lakes provided an important subsistence base, and marine resources were mainly related to raw material needs. The narrower breadth of resources is reflected in the osseous production, where implements were made from seal bones. The lithic technology exhibits local adaptations over time – in the form of a simplification of the technology – that we relate to sedentism and increases in risk management and external networks.

This article represents a basic comparison of gouge collections from three different sites (Esh Shaheinab, Fox Hill and Kadero). These sites have produced important collections of lithics from the Early Neolithic period in central Sudan. Gouges were chosen as an important marker of various activities, and these were studied on the basis of examining this type of artefact. This paper presents basic observations on the technology and function of these artefacts.

The Late Pleistocene, Early and Middle Holocene Nubian cultural sequence was constructed after the pioneering work done in Nubia in the 1960s (Irwin et al., 1968; Wendorf ed. 1968c; Marks 1970; Nordström ed. 1972). Most of the prehistoric sites located by the expeditions during the Nubian Campaign were surface concentrations and their dating was made on the basis of their location on ancient Nile deposits attested at different levels: the Dibeira-Jer, Ballana, Sahaba, Birbet and Arkin formations (De Heinzelin 1968). Absolute elevation was also considered as relevant to a site’s date. Within this cultural sequence, the Qadan (Shiner 1968a) was usually associated with the Sahaba Formation, whose beginning was more or less established at 16,500 BP (De Heinzelin 1968), and the Jebel Sahaba cemetery (Site 117) was attributed to this same cultural phase. The Qadan sequence has been already discussed by the author (Usai 2008a) in a paper demonstrating that Shiner’s hypothesis that the Abkan Neolithic complex originated directly from the Qadan needed revision. This contribution continues this discussion but to suggest that it now appears that the Jebel Sahaba cemetery cannot be possibly associated with the Qadan. In doing so, it notes some possible discrepancies and some important factors.

Current perspectives of stone tool technology tend to emphasize homogeneity in tool forms and core reduction strategies across time and space. This homogeneity is understood to represent shared cultural traditions that are passed down through the generations. This represents a top-down perspective on how and why stone tools are manufactured that largely restricts technological agency to experts, adults and teachers. However, just as bottom-up processes driven by children and youth influence technological innovation today, they are likely to have played a role in the past. This paper considers evidence from the archaeological record of early Homo sapiens’ lithic technology in Africa that may attest to our long history of bottom-up social learning processes and learner-driven innovation. This evidence includes the role of emulative social learning in generating assemblages with diverse reduction strategies, a high degree of technological fragmentation across southern Africa during some time periods, and technological convergence through the Pleistocene. Counter to some perspectives on the uniqueness of our species, our ability to learn independently, to ‘break the rules’ and to play, as opposed to conforming to top-down influences, may also account for our technological success.

On this paper we show records of Pleistocene fauna from the archaeological site of PayPaso 1, located near of the Quarai River. On this site we recovered two extinct species, Equus sp. (ancient horse) e Glyptodon sp. (giant armadillo), direct associated with lithic artifacts. Our results indicate that these extinct mammals lived in the beginning of the Holocene (9,600 – 9,100 years 14C BP), based on nine 14C age results obtained by AMS (Accelerator Mass Spectrometry) measurements. In this work, these results are compared with others in South America. Human adaptation, lithic technology,Pleistocene fauna extinction and climate change at the transition between leistocene-Holocene are also discussed.

The transition from the dart to the arrow, and the commensurate changes in lithic technology is poorly understood in the American Southwest. This transition has often been linked to shifts in sedentism and the increasing use of expedient flake tools. However, the relationship between the use of bifacial and core reduction strategies are conditioned by a variety of factors, and not primarily in response to the use of the bow-and-arrow, or simply sedentism. We, therefore, evaluate a series of potential factors which can be used to understand the variability exhibited in the use of biface and flake technologies. [ABSTRACT FROM AUTHOR]

During the Pleistocene-Holocene transition, the European archaeological records can be divided into two broad entities – the Epigravettian in the northern Mediterranean Basin and the industries characterized by the return of a well-developed blade technology in northwestern Europe. This large Western European techno-complex comprises several cultural traditions defined essentially by various types of projectile points. One of these cultures, the Laborian, occupies an area at the crossing of northern traditions (Ahrensbourgian) and the Epigravettian techno-complex. Situated between the Azilian and the Mesolithic, the Laborian (ca 12.5–11 Ka cal. BP) is, paradoxically, poorly defined in southwestern France where it was initially defined. In fact, data for this culture is essentially available in the surrounding regions and especially in northern and western France. Revaluation of key Laborian lithic assemblages as well as the discovery of new sites today allow to draw a new picture of the various cultural traditions occupying this large area around 12 Ka cal. BP. Despite the scarcity of data on hunted fauna, we can observe the dominance of the exploitation of large game typical of open temperate landscapes. Osseous industry is also rare but we note the maintenance of bone barbed points in few sites. Artistic. conventions (engraved pebbles or bones) show several symbolic innovations, such as the development of a unique zoomorphic art. Lithic hunting weaponry essentially based around pointed elements, much like during the Azilian, allows to highlight two chronological phases along the Laborian culture: an older phase with straight backed points with truncated bases (Malaurie points) and bitruncated backed blades ("rectangles") and a recent phase with pointed backed bladelets (Blanchères points) and bitruncated trapezoids. The production of large, standardized, straight blades with flat cross-sections during the Laborian reveals clear similarities with concepts recognized in Belloisian collections from Northern France even if blade lengths rarely reach the standards known on these sites. Finally, the technological study of domestic stone tools and hunting weaponry is an effective means for reconstructing larger scale evolution processes influencing these last Pleistocene societies and the persistence of their traditions into the European Mesolithic.

The Tardiglacial of Portugal has been associated with the Magdalenian culture and lithic industries characterized by tool miniaturization, a diversity of microlith types, and the absence of a intentional blade production. The technological characterization, the chronology and the phasing of the Portuguese Magdalenian have been defined based on data recovered from open-air sites of the Estremadura region (Central Portugal). This paper presents an overview of the research undertaken over the last twenty-five years, including results from research and preventive archaeology fieldwork outside this region, namely in the Côa, Sabor and Vouga Valleys (northern Portugal), as well as in the Guadiana Valley and Algarve regions (southern Portugal). Our chronological boundaries are the Greenland Stadial 2-1b and the 8.2 ka event, from Early Magdalenian to Early Mesolithic. Regarding vegetation, deciduous Quercus underwent expansion during the warm phases of the Tardiglacial and retracted during cold ones, when pines increased. After the Solutrean, the faunal assemblages show a decrease in the variability of the represented species and an increase in fish, birds, small mammals and rabbits (Oryctolagus cuniculus). Concerning the cultural sequence, the Middle Magdalenian remains uncharacterised. After the Upper Magdalenian, and thenceforward, the use of local raw materials and of cores-on-flakes (burin or carinated endscraper type) for bladelet production gradually increased. In terms of lithic armatures typology, a four-stage sequence can be discerned: 1) Upper Magdalenian with axial points rather than backed bladelets, quite common in previous phases; 2) Final Magdalenian with an increase in the diversity of armature types; 3) Azilian with geometric microliths, curved backed points (Azilian points) and Malaurie points, and 4) Early Mesolithic without retouched bladelet tools or at best a persistence of Azilian armature types. There were some changes in the Palaeolithic rock art of the Douro basin between phase 3 (Final Magdalenian) and phase 4 (Late Azilian): figurative animal representations give place to animal depictions characterized by their geometrical bodies, often filled-in, and red deer becomes the best-represented animal.

This work deals with Late Upper Palaeolithic (Azilian and Laborian) lithic industries in the French Pyrenees. Assemblages are compared at an interregional level in order to contextualize and clarify this period. Since its discovery at the end of the 19th century, the Azilian was characterized by its specific lithic industry (backed points), osseous artefacts (harpoons) and artistic remains (painted pebbles). However, new discoveries have shed new light on our understanding the Azilian. Six lithic assemblages were examined in this study: Rhodes II (Ariège), Troubat (Hautes-Pyrénées), La Tourasse (Haute-Garonne), Le Poeymaü (Pyrénées-Atlantiques), Gouërris (Haute-Garonne) and Pagès (Lot), allowing us to investigate the evolution of the Azilian and Laborian technocomplexes and to comparatively evaluate this process at the scale of Western Europe. The beginning of the Azilian in the Pyrenees differs from what is observed in the northern Aquitain Basin; the Magdalenian seems to persist until 14 200 cal. BP, while the Early Azilian is only observed in the Basque Country. However, during the recent phase some common traits are identified at a larger scale (France, Pyrenees, Cantabria), most notably a technological simplification. Still, the Pyrenean Azilian (between 14 200 and 12 500 cal. BP) preserves its regional lithic signature, defined by the presence of double backed points, small scrapers and the use of bipolar reduction on an anvil. The Laborian, sporadically present in the Pyrenees, may indicate a later technical reinvestment, characterized by a more regular and straight production of lamino-lamellar blanks, which is a trend that appears to be observed in the whole Western Europe around 12 500 cal. BP. [ABSTRACT FROM AUTHOR]

For the first time we compare lithic production systems from the three archaeological phases identified in the Iberian Mediterranean region between 14.5 and 10.5 ky cal BP: final Magdalenian, microlaminar Epipalaeolithic and sauveterroid Epipalaeolithic. These phases coincided with rapid palaeoenvironmental changes, whose effects on a peripheral region of southern Europe require a regional analysis. The basic blanks used in all three phases were blades and bladelets and there is considerable typological homogeneity. The results obtained in the study of the three phases identified at Coves de Santa Maira provide new grounds for discussion about lithic production systems during the Pleistocene–Holocene transition. Through this study it has been possible to establish the local and regional origin of the raw materials. At the same time, it has been observed that the standardisation typical of the classic Magdalenian decreased and there was an increase in more flexible and opportunistic chaînes opératoires , in addition to the absence of some stone points that are characteristic of more northern facies and cultures. The results have made it possible to contextualise the known data for the central–southern region of the Iberian Peninsula, allowing us to draw up a regional model of lithic production systems and assess the continuity or break between the three phases, as well as providing new possibilities to investigate the relationship with other facies and regional groups.

What happened at the transition between late Pleistocene and early Holocene in Italy and the Western Balkans remains up to now an unresolved question. While in recent years, research has been conducted in several regions, it is still difficult to propose a synthetic model for the changes that occurred in material cultures during this period. Multiple causes may explain this, but the apparent diversity of scenarios illustrated by each region seems to be the most explanatory. Terms such as terminal or final Epigravettian, Epipaleolithic, Romanelian and Sauveterrian, used in certain contexts, do not have a generally accepted definition. Some of these terms have been criticized and, at least, their definition should be reevaluated in accordance with modern methodological norms. Nevertheless, they indicate an actual diversity of regional and chronological expressions that we should describe precisely and integrate into a comprehensive model for the changes that occurred in this critical phase of the Late Upper Paleolithic. On a global scale, it has been argued that in contrast to what has been described in Western Europe for example, no discontinuity between the end of the Epigravettian and the first Mesolithic is evident. To better understand this period and its dynamics, it is necessary to initiate a hierarchical analysis of the elements of unit and variability across time and among the different regions. In order do to so, it is necessary to engage (1) a critical review of the available data and (2) a comparative technological analysis of different assemblages. This paper is a first step in this direction. We focus especially on the current study of two assemblages from Italy and the Western Balkans: grotta della Continenza (Central Italy) and Medena Stijena (Montenegro). We also include published data from the recent study of the sequence of grotta del Cavallo (Southern Italy). To sum up, we discuss the chronological and geographical variability in Italy and the Western Balkans based on a regional synthesis. [ABSTRACT FROM AUTHOR]

The character of lithic industries in southwest China is still unclear due to the limited number of dated and well-studied sites reported. Although a diversity of prehistoric cultures in this geographic area has long been proposed, the term "cobble-tool industry" was often applied to different lithic assemblages which included tools made on cobbles or pebbles. However, this term loses its validity when exploring the diversity presented in the assemblages and renders it difficult to make comparative studies with neighboring industries in mainland Southeast Asia and southern China. Therefore we use the chaîne opératoire approach to distinguish the operational sequences that reveal the processes and objectives of lithic production and to construct uniform criteria for comparison between different lithic industries. Here we present the lithic assemblage of the Tangzigou open-air site (Yunnan Province, southwest China) from a technological perspective. We argue for an original technological solution to conduct subsistence tasks in this industry, because abundant bone tools are associated with the stone tools. Therefore Tangzigou may provide an ideal case to discuss the coexistence of organic and lithic tools within an industry which developed in a subtropical environment in southern China. The lithic industry of Tangzigou, though dominated by the concept of shaping (façonnage), was very different from those "Hoabinhian Assemblages" in the Lancang River valley (upper reach of the Mekong River) in western Yunnan, and thus it could be another argument supporting the diversity and originality of prehistoric cultures in Southwest China, and also possibly influence on the prehistory of the nearby region of mainland Southeast Asia.

The applicability of the three stage Paleolithic sequence (Lower, Middle, Upper) in eastern Asia that is used in the western Old World has long been a debated issue. The crux of the discussion is whether a distinct "Middle Paleolithic" ("MP") is present in the eastern Asian record, especially north China. Recently, the artifacts from the Lingjing site (2005–2016), in northern China, have been argued to be potential representative of a "Chinese Middle Paleolithic" ("CMP"). In this paper, we introduce a thorough analysis on a newly discovered lithic assemblage from the 2017 excavation of the Lingjing site. We found that simple free-hand hard hammer percussion is the dominant core reduction strategy with only a very small frequency of atypical, bi-conical discoidal cores. When considering other contemporary sites in northern China (e.g., Xujiayao and Banjingzi), Lingjing belongs to a small tool tradition that is widespread throughout northern China. The Lingjing artifacts do display some obvious differences in core reduction and lithic retouching techniques from those typical of the Lower/Early Paleolithic (or Mode 1) assemblage pre-40 ka in the Chinese Paleolithic. The diversity of characteristics of lithic technology from Lingjing and other contemporary sites in north China show the complexity of the Chinese Early Paleolithic, rather than a simple monotonous stone tool tradition.

The lack of a standard protocol for analyzing and comparing multiple assemblages of lithic artifacts has hindered the advance of a better understanding of the cultural diversity associated to prehistoric hunter-gatherer groups. This was the case of Brazilian archaeologists that for many decades associated lithic stemmed point assemblages to a cultural entity known as "Umbu Tradition". However, most associations of assemblages to this "tradition" have been made regardless of the type of lithic points, as well as ignoring other elements related to the lithic industry, settlement patterns, among others. As a result, since the 1980s, several studies have been questioning the validity of such Tradition. Recent research has proposed new definitions for the previously associated Umbu Tradition lithic industries based on the stemmed points typology. However, no raw data on the technological analysis of such points have ever been presented. This article proposes a protocol for the technological study of lithic points that allows the application of descriptive statistics and multivariate analysis to verify if these types present or not significant differences. We present new data on the technological analysis of 501 lithic points from sites located in the supposed Umbu Tradition coverage area and period, as well two new Early Holocene C14 dates for one of the studied sites (Caetetuba site). Our results corroborate previous propositions of discarding Umbu Tradition as a valid cultural entity, as well as new typologies for the points. We also show that our protocol is suitable to unravel potential cultural patterns regarding many attributes in lithic points as well as to explore if there are significant differences among previously defined types.

Nasera Rockshelter hosts a highly continuous sedimentary record, containing a wide array of archaeological remains from Middle Stone Age, Later Stone Age and Pastoralist occupations. Excavated by L. Leakey and M. Mehlman, geological studies carried out by R. Hay included granulometric and general mineralogical analyses but lacked individualized, detailed description and interpretation of each of the 25 levels exposed. This study presents updated detailed geological descriptions and interpretations of 17 levels exposed during excavations in 2018. [ABSTRACT FROM AUTHOR]

Knowing to what extent lithic cores have been reduced through knapping is an important step toward understanding the technological variability of lithic assemblages and disentangling the formation processes of archaeological sites. In addition, it is a good complement to more developed studies of reduction intensity in retouched tools and provides information on raw material management or site occupation dynamics. This paper presents a new methodology for estimating the intensity of reduction in cores and tools on cobbles, the Volumetric Reconstruction Method (VRM). It is based on a correction of the dimensions (length, width, and thickness) of each core from an assemblage. The median values of thickness and platform thickness of the assemblage’s flakes are used as corrections for the cores’ original dimensions, after its diacritic analysis. Then, based on these new dimensions, the volume or mass of the original blank are reconstructed using the ellipsoid volume formula. The accuracy of this method was experimentally tested, reproducing a variety of possible archaeological scenarios. The experimental results demonstrate a high inferential potential of the VRM, both in estimating the original volume or mass of the original blanks and in inferring the individual percentage of reduction for each core. The results of random resampling demonstrate the applicability of VRM to not size-biased archaeological contexts. [ABSTRACT FROM AUTHOR]

The Iberomaurusian lithic industries in the Maghreb are known for their microlithization characteristics beginning ca. 25 ka cal BP. The analyses of the Iberomaurusian lithic assemblages in Algeria have mostly focused on typological and stylistic issues. These are good for distinguishing the various archaeological entities encountered in the region but inadequate for understanding the techno-economic behaviors that these industries supported. A technological approach to analysis allows for the recognition of the choices made by the knappers throughout the core reduction processes, the blank production, the transformation of blanks into tools, and the debitage methods and techniques. It has proven useful for understanding not only lithic production process but also the roles that lithic tools played in various subsistence economies. Hence, this paper uses a technological approach to reanalyze the lithic assemblages from Tamar Hat, Rassel, and Columnata. The lithic industries of these three sites are characterized by the tendency toward microlithization as attested by the presence of small chipped stone artifacts on diminutive blanks. The results suggest that the hunter-gatherer populations of the Maghreb produced microliths using a wide range of technological options during the Late Pleistocene. The study also reveals diachronic changes in the production modalities of the microliths. These changes are likely related to variations in hunting strategies in different ecological niches and as adaptive strategies to various paleoclimatic events of the Late Pleistocene.

The Iberomaurusian lithic assemblages from Ifri El Baroud (northeast Morocco) are discussed from techno-economic, typological, and functional points of view. The site preserves an archaeological sequence spanning the period ca. 23,000–13,000 cal BP. The analysis of the lithic materials from the sequence highlights the diachronic changes in human behavior. Results show a strong relationship between paleoenvironmental shifts and changes in settlement strategies and lithic production. [ABSTRACT FROM AUTHOR]

Endscrapers, the most abundant tool class at Eastern North American Paleoindian sites, are flaked stone specimens predominately used for scraping hides. They are found broken in high frequencies at these sites, a pattern that has been attributed to use. However, previous experimental and ethnographic research on endscrapers suggests that they are difficult to break. We present a series of replication experiments assessing the amount of force required for endscraper breakage, as well as the amount of force generated during human use. We also analyze which morphometric variable best predicts the breakage force. Our results demonstrate that the force humans can generate is far below the breakage force, which is best predicted by endscraper thickness. Finally, we examine an actual Paleoindian endscraper assemblage, concluding that human use was not the cause for breakage. Taphonomic factors such as plowing, or trampling, are a much better potential explanation for the high breakage frequencies present at Paleoindian sites. [ABSTRACT FROM AUTHOR]

The Fox site (5WL8848) is a collection of Clovis artifacts from the Kersey Terrace in northern Colorado. In the early 1970s, land-leveling for the construction of a large turkey farm near the town of Kersey revealed chipped stone tools in eolian sand dune sediments at the southern margin of the Kersey Terrace of the South Platte River. Max Fox and other employees of the turkey farm collected three complete Clovis projectile points, several fragmentary points, bifaces, and flake tools at the site. Fox forwarded information about the site to professional archaeologists in the early 1990s, but it was largely ignored after a brief geoarchaeological investigation. The Fox site contains a moderate frequency of chipped stone tools relative to other known Clovis assemblages in Colorado's South Platte River basin, and it is located within a concentration of Paleoindian kill-butchery sites on the Kersey Terrace. Despite several contextual issues the Fox site is a significant contribution to the Clovis record of Colorado. [ABSTRACT FROM AUTHOR]

The last hunter-gatherers of the central and western Mediterranean are associated with the Castelnovian technocomplex, which developed during the seventh millennium BC and is characterized mainly by its lithic industries, which reflect important changes that occurred during the Late Mesolithic: debitage from this time is oriented towards blade production by pressure-flaking and the manufacture of special tools, such as trapezes (made by the microburin technique) and notched blades. Although rare, Castelnovian sites have been identified in the wider Adriatic region of south-central Italy, Albania, Montenegro and the Italian and Slovenian Karst. However, it seems that the Croatian coast and its hinterland in the eastern Adriatic lack any traces. No sites were found in Dalmatia and only a few questionable surface finds come from Istria. This study explores whether this absence is due to historical factors, such as depopulation during the Late Mesolithic or the region being outside the Castelnovian expansion route, or whether it is because of a combination of taphonomic causes (such as loss of sites by marine transgression) and lack of previous research. The paper also focuses on the hypothesis that the presence of the last hunter-gatherers can be detected indirectly through the persistence of Castelnovian elements in the oldest Neolithic Impressed Ware assemblages of the eastern Adriatic. I further propose that Castelnovian traits are observable in the Impressed Ware assemblages of Istria. This Mesolithic tradition consists of the use of local flint, blade production by indirect percussion and 'simpler' forms of pressure flaking in lithic production, while marine resources remain an important food resource.

Lake Cardiel basin (Central-West Santa Cruz) has been object of archaeological research seeking to discuss the relationships between climatic/environmental and social change during the Holocene. These researches characterized the basin as a region of late settlement in relation to neighboring spaces. In this basin a drying process during the Holocene generated a reorganization of local populations. This paper approaches the problem from a particular site, Alero Los Guanacos 1, to discuss the way in which these processes are presented at a smaller scale. The site presents occupations during the mid and late Holocene. The technology recovered there is analyzed, and taking this into account, variations in the site use over time are discussed. Some of these variations differ from the general overview known for the basin. It is concluded that these differences are the result of the differential role of the different spaces in the settlement process. [ABSTRACT FROM AUTHOR]

The Oscurusciuto rock shelter (southern Italy) is crucial for the understanding of Neanderthals’ subsistence and settlement strategies as it contains a ~ 6-m-thick reliable deposit made up of several Middle Palaeolithic levels. This paper focuses on level SU 14, a 60-cm-thick deposit of volcanic tephra containing traces of human occupation only in the few upper centimetres. Geochemical and mineralogical features of SU 14 deposits allowed their correlation to the ‘Mount Epomeo Green Tuff’ eruption, which came from Ischia volcano and dated to ~ 55,000 years bp. The pyroclastic materials injected into the atmosphere caused an ash fall-out over a large part of southern Italy, resulting in the alteration of ecosystems. Sedimentological data demonstrate that the formation of SU 14 is attributable to a short-term event. Moreover, the lithic behaviour indicates that Neanderthals used the shelter mainly to perform specific activities related to the first phases of the reduction sequence (i.e. selection and import of pebbles into the site, initialisation and production of the first generation of debitage objectives, and introduction of already finished tools). Consequently, the layer SU 14 raises questions regarding the impact of deposition of volcanic ash on human communities, offering the opportunity to investigate the settlement and technological choices made by Neanderthals who were constrained by such an adverse environmental event.

The beginning of the Middle Palaeolithic in Western Europe is traditionally associated with the emergence of new, more complex and standardised debitage technologies, such as Levallois technology. These changes occurred in the archaeological record between MIS 9 and MIS 6. This paper aims to evaluate the processes of technical change at work in Southern France, tracking innovations and persistent behaviours and potential shifts, to describe the process of transition and compare the Southeast and Southwest of France. We revised several major sites from Ardèche and Dordogne through the technological analysis of seven lithic assemblages in areas rich in good-quality raw materials, mostly flint. Technological analysis shows common features in lithic strategies and industries that can all be attributed to the Early Middle Palaeolithic. The features are a diversity of debitage methods and spatiotemporal management of the chaînes opératoires (ramification and artefact mobility). At the same time, algorithmic methods (Système par Surface de Débitage Alternées: SSDA) continue to be used, in the same way as large cutting tools (LCTs), although they are rare (pebble tools, bifaces and ‘mixed matrices’). These LCTs are persistent technologies from the Acheulean technocomplex. Gradual mosaic-type changes in the lithic record are particularly well demonstrated through the sequence of Orgnac 3, where a local onset of Levallois technologies appears to occur. Both in the Southeast and Southwest of France, the Lower to Middle Palaeolithic transition records gradual and asynchronous behavioural changes as early as MIS 9 to MIS 6. These shifts are not only due to increased hominin cognition. Abilities of human groups to adapt to diversified environments and regional cultural processes may also have played a key role. Several lithic technocomplexes coexisted between MIS 9 and 6 in these two areas and although differences in local strategies are obvious, similar trajectories towards MP behaviour can be detected.

Roccia San Sebastiano is a tectonic-karstic cave located at the foot of the southern slope of Mt. Massico, in the territory of Mondragone (Caserta) in Campania (southern Italy). Systematic excavation has been carried out since 2001, leading to the partial exploration of an important Pleistocene deposit, extraordinarily rich in lithic and faunal remains. The aim of this paper is to (1) present the stratigraphic sequence of Roccia San Sebastiano, and (2) technologically describe the lithic materials of squares F14 t18, t19, t20; E16 t16, t17, t18 recently recognised as Uluzzian. The stratigraphic sequence is more than 3 m thick and dates from the Middle to the Upper Palaeolithic. It contains different techno-complexes: Gravettian, Aurignacian, Uluzzian and Mousterian. In the Uluzzian lithic assemblage mostly local pebbles of chert were used in order to produce small-sized objects. The concept of debitage mainly deals with unidirectional debitage with absent or fairly accurate management of the convexities and angles; the striking platforms are usually natural or made by one stroke. It is attested the use of both direct freehand percussion and bipolar technique on anvil in the same reduction sequence. Amongst the retouched tools the presence of two lunates is of note. This study of the Roccia San Sebastiano Uluzzian lithic complexes is significant for understanding the dynamics of the transition from Middle to Upper Palaeolithic in the Tyrrhenian margin of southern Italy.

Defining the processes involved in the technical/cultural shifts from the Late Middle to the Early Upper Palaeolithic in Europe (~50-39 thousand years BP) is one of the most important tasks facing prehistoric studies. Apart from the technological diversity generally recognised as belonging to the latter part of the Middle Palaeolithic, some assemblages showing original technological traditions (i.e. Initial Upper Palaeolithic: Bohunician, Bachokirian; so called transitional industries: Châtelperronian, Szeletian, Lincombian-Ranisian-Jerzmanowician, Uluzzian; Early Upper Palaeolithic: Protoaurignacian, Early Aurignacian) first appear during this interval. Explaining such technological changes is a crucial step in order to understand if they were the result of the arrival of new populations, the result of parallel evolution, or of long-term processes of cultural and biological exchanges. In this debate Italy plays a pivotal role, due to its geographical position between eastern and western Mediterranean Europe as well as to it being the location of several sites showing Late Mousterian, Uluzzian and Protoaurignacian evidence distributed across the Peninsula. Our study aims to provide a synthesis of the available lithic evidence from this key area through a review of the evidence collected from a number of reference sites. The main technical features of the Late Mousterian, the Uluzzian and the Protoaurignacian traditions are examined from a diachronic and spatial perspective. Our overview allows the identification of major differences in the technological behaviour of these populations, making it possible to propose a number of specific working hypotheses on the basis of which further studies can be carried out. This study presents a detailed comparative study of the whole corpus of the lithic production strategies documented during this interval, and crucial element thus emerge: 1. In the Late Mousterian tools were manufactured with great attention being paid to the production phases and with great investment in inizializing and managing core convexities; 2. In contrast, Uluzzian lithic production proceeded with less careful management of the first phases of debitage, mainly obtaining tool morphologies by retouching. 3. In the Protoaurignacian the production is carefully organized and aimed at obtaining laminar blanks (mainly bladelets) usually marginally retouched. These data are of primary importance in order to assess the nature of the "transition" phenomenon in Italy, thus contributing to the larger debate about the disappearance of Neandertals and the arrival of early Modern Humans in Europe.

In the Brazilian state of Rio Grande do Sul, the term cerrito was traditionally used to designate archaeological phenomena that emerge in the form of mounds in different landscapes. Except for recent research developed in the southwestern region of the Patos Lagoon, few advances have occurred since the 1980s in the study of cerritos in Brazil. This article presents an analysis of the lithic industries of sites with mounds in the southwestern region of the Patos Lagoon and in the central region in the current territory of Rio Grande do Sul. The results, along with other data from the sites, suggest that coastal sites were occupied by sedentary fisher-hunter-gatherers, who also possibly domesticated certain plants. Lithic material was scarce there and was mainly produced from pebbles and quartz cobbles using the anvil technique. In contrast, central region formations presented mounds on outcrops, using land, pebbles, and boulders; the area was occupied by a hunter-gatherer group that had projectile points and other instruments carved mainly by façonnage and débitage.

Discovered in March 2015, the sites of DAJ‐112 and DAJ‐125 in the Al‐Jawf province of northern Saudi Arabia consist of a large collection of surface lithic artefacts that can be compared to well‐known Pre‐Pottery Neolithic (PPN) B technology from the Levant: the two sites include bidirectional blade technology with naviform core preparation and opposed platforms surface exploitation, as well as burin production at a wide scale. Other surface scatters have been identified during the 2013 and 2015 surveys, showing these two sites are not isolated in Al‐Jawf, as rather important occurrences of Early Holocene technology have been identified across the region. Although the sites from Al‐Jawf are surface occurrences and not radiometrically dated, the finds have proven to be extremely significant, representing a southward incursion of classic naviform cores‐based technology, thus expanding the geographical distribution of this technology beyond the Levant. By addressing the lithic evidence from northern Arabia, the expansion and/or influence of PPN populations and cultural elements will be discussed. [ABSTRACT FROM AUTHOR]
