The layer B is one of the lower layers of the long stratigraphic sequence of the Kamyana Mohyla 1 site. The layer B received eight new AMS radiocarbon dates that clarified its chronology: 7950–7300 calibrated years BC. They are in a reasonable correspondence with the dates for lower and upper layers. The lithic assemblage belongs to Kukrek cultural aspect. It is characterized by pencil-like conical cores, Kukrek inserts, Kukrek burins and Dęby burins, nongeometric microliths (oblique points). The assemblage finds close parallels in the sites of Kukrek, Ihren VIII, Melnychna Krucha SU4 and Domchi-Kaia. They can be united into Kukrek sensu stricto cultural unit. The overlying layer C yielded somewhat different complex that finds parallels in the materials of the so-called “Kukrek cultural tradition.” Due to clear stratigraphic position of these units in the Kamyana Mohyla 1 sequence, we are able to differentiate Kukrek sensu stricto and “Kukrek cultural tradition” and suggest their respective chronological positions.

Surveys near the village of Stumpertenrod revealed one of the largest Mesolithic assemblages in Germany. As a consequence of agricultural activities, the archaeological layers were partly eroded and the lithic artifact consisted mainly of surface finds. Between 1964 and 1966 Wolfgang Taute–a key-figure for the study of the Mesolithic in Europe–opened a trial-trench. Due to a lack of organic material, the campaign did not lead to the expected outcome and the site slowly fell into oblivion. The following article presents the results of typo-technological analyses of the lithic assemblage discovered in the course of the excavation. It provides new insights into the subsistence strategies of people during the early Holocene and re-integrates this significant site in current frameworks and debates. Furthermore, an interregional comparison of archaeological features and topographic parameters involving modern theoretical and methodological approaches, leads to a better understanding of the Early Mesolithic in the western part of Central Germany.

This paper presents the results of the analysis of a late Acheulean horizon from the EDAR 135 site, which was discovered in the Eastern Desert, Sudan, in an area heavily transformed by modern mining activity. A lithic assemblage was discovered there, within a layer of gravel sediments formed by a paleostream in a humid period of the Middle Pleistocene. This layer is OSL dated between 220 ± 12 and 145 ± 20 ka (MIS 7a/6). These dates indicate that the assemblage could be the youngest trace of the Acheulean in northeastern Africa. Technological analysis of the lithics reveals different core reduction strategies, including not only ad hoc ones based on multiplatform cores, but also discoidal and prepared cores. The use of prepared core reduction methods has already been confirmed at other Late Acheulean sites in Africa and the Middle East. Microwear traces observed on lithic artifacts could relate to on-site butchering activities. publishedVersion

Seeman, Morris, and Summers misrepresent or misunderstand the arguments we have made, as well as their own previous work. Here, we correct these inaccuracies. We also reiterate our support for hypothesis-driven and evidence-based research.

The neutral model of stone procurement developed by Brantingham (2003, 2006) provides a formal means to investigate the formation of lithic discard patterning under changing forager mobility conditions. This study modifies Brantingham's (2006) Lévy walk model to examine the influence of discard probability on the spatial distribution of raw material abundance. The model outcome shows that forager movement and tool discard probability have similar effects on the simulated patterns of raw material transport, so it is difficult—if not impossible—to differentiate the respective influence of the two factors from distance to source distributions alone. This finding of equifinality complicates the task of interpretating hominin mobility from archaeological distance to source data, particularly in settings such as the Middle-Upper Paleolithic transition, which is marked by an important reorganization in hominin lithic technology that may have affected stone tool discard probability.

The study of raw materials is an essential step in lithic analysis, regardless of the age, provenance, and technology of the assemblages. As in many other contexts of the Paleolithic, researchers of the Middle Stone Age (MSA) in southern Africa have often focused their attention on fine-grained, non-local rock types, such as silcrete. Here, I spotlight raw materials considered to be of lower suitability for knapping and frequently acquired from local sources. Due to their coarse-grained nature, artifacts from rock types such as calcrete, sandstone, and quartzite might show attributes that are different from finer-grained materials. Some of these knapped stones even constitute the substrate of the sites they are from, at times resulting in their neglect or not being recognized as anthropogenic artifacts. Knapped vein quartz features sharp and durable edges, but its complicated fracture mechanics hamper comparative analysis and provide methodological challenges. In this study, raw materials from different transport distances and with different presumed qualities are compared in terms of their roles in MSA lithic technology and settlement patterns. In the first step, the article focuses on the open-air special-purpose camp of Hoedjiespunt 1 (HDP1, Western Cape) and the rockshelter residential site of Sibudu (KwaZulu-Natal), especially on assemblages dated between ~ 130–100 and ~ 58 ka. Subsequently, I review relevant materials for the southern African MSA. At HDP1 and Sibudu, local raw materials of lower knapping suitability assume several roles, from the “staple” material for all manufacturing stages to special-purpose and “add-on” functions. In the broader southern African region, MSA knappers also used these rock types in a flexible manner with gradual differences but also similarities to their use of finer-grained raw material. These differences depend on a complex interaction of raw material availability, differential site use, and the position of the localities in the settlement system.

Neolithization was a complex, protracted process of domestication, sedentarization, and technology change that occurred in various combinations in various times and places around the world. Understanding the causal relationships among those and other important human behaviors remains an analytical challenge. This study examines Neolithization through the lens of lithic artifact variation in the Lake Titicaca Basin, Peru. Drawing on previous lithics research, we outline a synthetic model linking changing diet, mobility, and projectile technology to predicted trends in lithic assemblages. The expectations are then compared to two large, well-dated lithic assemblages from the Titicaca Basin—one from the Middle/Late Archaic forager site of Soro Mik’aya Patjxa (8.0–6.5 cal. ka) and the other from the Terminal Archaic horticultural site of Jiskairumoko (5.2–3.4 cal. ka). We find that the strongest signal in lithic technology change is related to the introduction of archery technology. Signals for subsistence change and declining mobility are relatively weak. The results suggest an early but unconfirmed adoption of archery technology in the Terminal Archaic Period with major transitions in mobility and diet likely to have occurred subsequently in the Terminal Archaic or Formative periods. The findings are consistent with a behavioral model in which changes in projectile technology played a prominent role in the evolution of resource intensification and residential sedentism as well as resource privatization and sexual division of labor in the high Andes.

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.

Vorganjska peć važno je prapovijesno pećinsko nalazište smješteno na padini brda Organ iznad Batomlja kraj Baške na otoku Krku. Sredinom 20. stoljeća ovo, kao i druga pećinska nalazišta na kvarnerskim otocima, počinje istraživati Vladimir Mirosavljević. Zahvaljujući rezultatima njegovih istraživanja Vorganjska peć, zajedno s Jami na Sredi na otoku Cresu te Velom špiljom na otoku Lošinju, postaje značajan izvor podataka o neolitiku Kvarnera i time neizostavni dio rasprava o tome razdoblju na istočnojadranskoj obali.

The beginning of the Neolithic in the Adriatic region dates back to approximately 6000 cal BC. The appearance of Impressed Ware pottery in an area that roughly covers the Strait of Otranto to the coastal plains of Southern Istria marks its generic development. By combining lithic, economic and paleoenvironmental data we propose a new arrhythmic model for framing Neolithisation in the Adriatic region. One the one hand, the data available suggest that in the south-central part of the basin (Dalmatia and Apulia) the transition to farming was relatively quick, resulting from the colonisation of an open landscape (seemingly linked to the “8, 2 ka event” and the installation of a dry climate). These newcomers settled mostly in the fertile plains of the Dalmatian and Apulian hinterland, basing their subsistence almost exclusively on agriculture and livestock, while the lithic blade production made of cherts from Gargano (southern Italy) testifies to important social aspects and complex management strategies (mining activities, more complex modes of pressure, specialized distribution networks). On the other hand, in the Northern Adriatic (Istria, Karst, Po plain? Marches?) the Neolithic emerged a bit later, possibly as a result of some form of acculturation. Although the data available are still scarce, some evidence suggest that the last Mesolithic groups played an active role in the process of neolithisation in these areas, as the presence of Castelnovian sites is documented and certain Castelnovian traditions are identified in the Impressed Ware lithic production (the use of local flint, lamellar production by indirect percussion and “simpler” forms of pressure flaking) and in the economy e.g. importance of fishing.

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.

Considerations of materiality and object-oriented approaches have greatly influenced the development of archaeological theory in recent years. Yet, Palaeolithic archaeology has been slow in incorporating this emerging body of scholarship and exploring its bearing on the human deep past. This paper probes into the potential of materiality theory to clarify the material dynamics of the Plio-Pleistocene and seeks to re-articulate the debate on the evolution of our species with materiality discourses in archaeology and the humanities more broadly. We argue that the signature temporalities and geospatial scales of observation provided by the Palaeolithic record offer unique opportunities to examine the active role of material things, objects, artefacts and technologies in the emergence, stabilisation and transformation of hominin lifeworlds and the accretion of long-term trajectories of material culture change. We map three axes of human–thing relations—ecological, technical and evolutionary—and deploy a range of case studies from the literature to show that a critical re-assessment of material agency not only discloses novel insights and questions, but can also refine what we already know about the human deep past. Our exploration underscores the benefits of de-centring human behaviour and intentionality and demonstrates that materiality lends itself as a productive nexus of exchange and mutual inspiration for diverging schools and research interests in Palaeolithic archaeology. An integrated object-oriented perspective calls attention to the human condition as a product of millennial-scale human–thing co-adaptation, in the course of which hominins, artefacts and technologies continuously influenced and co-created each other.

The valley of the Tolbor river featured one of the earliest traces of the Early Upper Paleolithic in Central Asia. The results of the authors’ study provided new opportunities for understanding the behavioral characteristics of the population in the Early Upper Paleolithic. Two sub-horizons (4b and 4a) were identified in horizon 4 of the Tolbor-21 site. Horizon 4b includes two independent area of activity associated with two fire pits. The results of a technological study demonstrated that the set of artifacts originating from the fire pits is characterized by a very high specific weight of cores and tools, including those of rare and peculiar types. The stage of regular manufacture of large pointed blades completely drops out of the technological sequence of the 4b horizon industry. The proportion of flakes with a natural crust is small. The authors concluded that the peculiar technical and typological appearance of the studied collection was accounted for by a behavioral situation where certain labor activities were performed near the fire pits, and a significant portion of the artifacts were transferred from this area to be used in another location.

Recent excavations at Leang Bulu Bettue, a limestone cave on the Indonesian island of Sulawesi, have yielded a collection of flaked chert and limestone artefacts with cortical surfaces that had been deliberately incised prior to or after the knapping process. The markings engraved on these artefacts, which were recovered from deposits ranging in age between approximately 30–14 thousand years ago (30–14 ka), comprise cross-hatched patterns and other non-figurative imagery. This behaviour is of interest because of the almost total absence of portable art in the Pleistocene record of Island Southeast Asia, and the long-standing idea that the early modern human lithic technology of this region was fundamentally simple and remained so over tens of millennia. Here, we take stock of these incised stone artefacts from methodological and theoretical perspectives. Our findings suggest that unless one is specifically examining cortex on stone artefacts for these fine incisions, they are easily overlooked, and hence, we focus on how to improve detection of these faint engravings. We also consider why the Leang Bulu Bettue inhabitants engraved stone tool cortex, a practice we regard as an enigmatic form of portable lithic art and an apparent example of the creative process being as important as the end product—if not more so. We conclude that otherwise unremarkable lithic assemblages in Island Southeast Asia and beyond may potentially harbour hidden evidence for symbolic content in the form of often barely perceptible markings on remnant cortical surfaces.

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.

Comparison of Late Paleoindian sites of the Great Plains and Rocky Mountains reveals 36 site components from 28 sites containing ground stone tools, including nine Cody Complex examples. Much of the ground stone use appears related to generalized activity, as few items have functionally specific forms. However, the Cody components have an unexpectedly higher number of grooved abraders as compared to other complexes. We note that Paleoindian examples contain wider u-shaped grooves compared to Late Prehistoric/Protohistoric abraders related to arrow production. We argue that Paleoindian abraders represent shaft abraders, used in the production of dart shafts within weaponry systems. We propose several hypotheses for the emergence of this technology during Cody times. The most parsimonious explanation is that the specific sites containing these abraders represent large camps, occupied for long periods and containing diverse chipped and ground stone assemblages.

Although anatomically modern humans emerged during the MSA, debates have focused on the timing for the development of cognitive thoughts, planning depth, and profound cultural innovations. While some scholars have attributed these qualities to the LSA population, others have proposed that the evolutionary modern human behaviors developed during the MSA. This paper is a contribution to this debate based on new excavations at Mumba site, Tanzania, occupied at different periods from the last Interglacial Maximum around 128,000 BP through the onset of Holocene ca. 12,000 BP. We use new ESR dates, geochronology of stratigraphic sequences, lithic technology and typological variability in archaeological assemblages to show gradual transformation, steadiness, and shared technological traits between the MSA and LSA occupation levels at Mumba. We concluded that there are no fixed boundaries between the late MSA and early LSA regarding cognitive thought and technological transformation in Africa.

The central geographical position of the Caspian region plays a key role in understanding the historical processes which took place in the territory of Central Asia. One of the important geological factors that influenced the processes of settlement in this region by ancient populations is the transgressive-regressive variability of the Caspian sea level and access to fresh water. There are dozens of Early Holocene sites on the Krasnovodsk Peninsula (Eastern Caspian), most of them being surface complexes. The interpretation of these complexes has so far been controversial due to the lack of stratigraphic context and absolute dating. Purpose. This paper analyzes the techno-typological characteristics of lithic tool assemblages assigned to Early Holocene industries from Eastern Caspian site Sai Djanurpa. The article also discusses the links of how the dynamics of the ancient shores of the Caspian influenced settlement dynamics in the region. Results. The conducted detailed techno-typological analysis of the lithic collection of Sai Djanurpa allowed to discern two distinct complexes. The two complexes defined by different technological and typological characteristics: types of chips, types of tools and metric indicators. The first complex is characterized by the exploitation of chalcedony flint for the production of blades by soft hammer percussion, by borer, end-scraper and retouched flakes in the toolkit. The second complex is associated with the use of chalcedony, sandstone and flint for the production of microbladelets by the pressure technique, from conical and frontal cores. The toolkit of the second set of complexes is characterized by bifacial narrow points, burins, ventral retouched microblades and micro-scrapers. Conclusion. Based on the analysis of the lithic assemblages, the geomorphological position of the site and the paleogeographic condition of the Caspian region, the authors assume that two different populations with two different material cultures inhabited the Sai Djanurpa site during the final Pleistocene – early Holocene and the middle Holocene.

The Uluzzian techno-complex is one of the first evidence for Homo sapiens successful dispersal in Europe. It develops from about 45 to 40 ka cal. BP, i.e., during the so-called “transition” from Middle to Upper Palaeolithic, the period in which Neandertals went extinct. The cave site of Castelcivita (southern Italy) contains a well-preserved stratigraphic sequence concentrated in this specific phase as it comprises Late-Final Mousterian, Uluzzian and Protoaurignacian layers. Here we present the technological study of the Uluzzian lithic assemblage found in layer rpi of this site. The study specifically focuses on the methods used to exploit cores, characterised by a low degree of technical investment in which management of the convexities and angles of debitage are almost absent. The most used percussion technique is bipolar striking on anvil. Despite they are not standardized, the obtained products show features which make them apt to be used in composite devices. The use of local raw materials, the production of small items and the marginal role of retouched pieces, among which some lunates are present, are also typical of the rpi assemblage. Based on these results we argue that the strengths of the Castelcivita rpi technological approach are its versatility, and the reduction of unnecessary costs related to raw material procurement, the configuration of the core and the management of the convexities. All these elements tend to the use of the available resources in the most productive way, without the final product losing efficiency, according to the concept “less is more”. A hypothesis possibly explaining this technical behaviour is provided in the conclusions.

Experimental archaeology continues to mature methodologically and theoretically. Around the world, practitioners are increasingly using modern materials that would have been unavailable to prehistoric people in archaeological experiments. The use of a modern material substitute can offer several benefits to experimental method, design, control, replicability, feasibility, and cost, but it should be directly compared to its “traditional” analogue to understand similarities and differences. Here, aluminum is introduced as a substitute for chert in prehistoric ballistics research because, critically, aluminum is safe, inexpensive, easy to process, and it and chert possess densities that differ by less than 4%. The aluminum casting process for replicating stone artifacts is presented, and it is shown that the aluminum castings are essentially identical in form, flake-scar patterning, and mass to their stone counterparts. We then present a proof-of-concept ballistics experiment that demonstrates no difference between aluminum and stone points in terms of target penetration.

The ability of early hominins to overcome the constraints imposed by the characteristics of raw materials used for stone tool production is a key topic on the discussion about the evolution of hominin cognitive capabilities and technical behaviours. Thus, technological variability has been the centrepiece on this debate. However, the variability of lithic assemblages cannot be correctly interpreted without understanding site occupational models and function and considering that individual tools represent specific discard moments in a continuous reduction process. In Europe, the earliest technological record is represented by the scarce and scattered Mode 1 technologies, often deriving from occasional occupations or restricted activity areas yielding unrepresentative assemblages. In this paper, we approach the technological behaviours exhibited by Lower Palaeolithic hominins from the subunit TD6.2 of the Gran Dolina site (Atapuerca, Burgos) by including the perspective of reduction intensity studies on the analysis of technological variability. Gran Dolina TD6.2 is a unique and extremely significant archaeological context, as it represents the oldest multi-layered unit of domestic hominin occupations in the Early Pleistocene of Europe. We use the Volumetric Reconstruction Method (VRM) to estimate the original volume of the blanks and quantify the reduction intensity of each core individually to characterise the reduction distribution patterns using Weibull probability distribution functions. Our results suggest differential raw material management in terms of reduction intensity, according to the characteristics of each lithology. This could reflect a solid understanding of raw material qualities and a certain degree of planning. Altogether, the continuity between knapping strategies through reduction denotes constant adaptation to raw material constraints as well as particular knapping conditions, rather than specific compartmentalised mental schemes. In conclusion, Homo antecessor toolmakers would have been situational knappers whose technological behaviour would be highly adaptive. This research constitutes the first reduction approach for the European Early Pleistocene assemblages that will lead to a referential framework for other European Early Pleistocene sites.

The Quina Mousterian is one of the well-defined Middle Paleolithic techno-complexes. Despite the pivotal research carried out in south-western France, the presence of this techno-complex across the rest of Europe is still poorly documented. Here we apply a techno-functional approach, combining technological and use-wear analyses, for reconstructing lithic core-reduction, tool-reduction, and tool use at De Nadale Cave, a single-layered Mousterian site with Quina features located in northern Italy and dated to the early MIS 4. Our results indicate that the flexible core reduction strategies identified at De Nadale show some similarities with the Quina knapping method, in addition to the adoption of centripetal methods on single surfaces. Variations of this scheme identified at De Nadale are the exploitation of lateral and narrow fronts which are aimed to the production of elongated, small blanks. A parallel, ramified reduction is applied to limace cores and Quina or demi-Quina scrapers having diversified purpose (mixed matrix). These blanks are exploited as tools and cores-on-flakes from which thinner, usable flakes or bladelets are detached. The use-wear identified on both scrapers and reaffutage flakes further confirm this behavior, demonstrating the use of both tools, albeit for different tasks (i.e., scraping and cutting). We discuss the ecological implications of this behavior within the Quina Mousterian. The high frequency of retouched tools and Quina or demi-Quina scrapers seems to accompany the highly mobile human groups associated with this techno complex and their seasonally organized subsistence strategies. Finally, by combining available multidisciplinary data on paleoenvironment, subsistence, and chronology, we were able to embed the neanderthal settlement of De Nadale in a regional and Western European frame, underlining the importance of the Quina Mousterian in Western Eurasia between MIS 4 and early MIS 3., Open access funding provided by Università degli Studi di Ferrara within the CRUI-CARE Agreement.

With over 200 peer-reviewed papers published over the last 20 years, 3D modelling is no longer a gimmick but an established and increasingly common analytical tool for stone artefact analysis. Laser and structured light scanning, photogrammetry, and CT scanning have all been used to model stone artefacts. These have been combined with a variety of different analytical approaches, from geometric morphometrics to custom reduction indices to digital elevation maps. 3D lithic analyses are increasingly global in scope and studies aim to address an ever-broadening breadth of research topics ranging from testing the functional efficiency of artefacts to assessing the cognitive capabilities of hominid populations. While the impact of the computational revolution on lithic analysis has been reviewed, the impact of 3D modelling on lithic analysis has yet to be comprehensively assessed. This paper presents a review of how 3D modelling in particular has impacted the field of stone artefact analysis. It combines a quantitative bibliometric analysis with a qualitative review to assess just how “revolutionary” 3D modelling has been for lithic analysis. It explores trends in the use of 3D modelling in stone artefact analysis, its impact on the wider lithic analysis field, and methodological, regional and theoretical gaps which future research projects could explore.

The role of experience during the exploration of lithic artefacts can be been investigated through multiple approaches. Knowledge can influence visual perception of the environment, whilst action “affordances” can be processed at the first sight of an object. In this study, we used eye tracking to analyse whether and to what extent archaeological knowledge can influence visuospatial attention whilst interacting with stone tools. Archaeologists were found to pay more visual attention to the middle region and the knapped surface. Differences between the visual exploration of choppers and handaxes were also found. Although the general pattern of distribution of the visual attention was similar to naïve subjects, participants with archaeological experience paid more attention to functionally relevant regions. Individuals with archaeological experience directed more attention to the upper region and the knapped surface of the tools, whilst naïve participants spent more time viewing the middle region. We conclude that although both groups could direct their attention to action relevant features in stone tools, functional affordances had a greater effect in subjects with previous experience. Affordances related to manipulation triggered lower attention and showed no differences between participants., Junta de Castilla y León and co-financed by the European Social Funds (EDU/574/2018), by MCIN/AEI/ of the Spanish Government co-financed by ERDF Funds (Atapuerca Project: PGC2018-093925-B-C31/32) and by the Italian Institute of Anthropology (ISITA).

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 human-level 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.

Predicting original flake mass is a major goal of lithic analysis. Predicting original flake mass allows for researchers to make estimations of remaining mass, lost mass, and other features. All these measures relate to the organization of lithic technology by past societies. The present work tests three different models to predict log of flake mass: multiple linear regression, random forest regression, and artificial neural networks (ANN). Estimations of flake mass were performed using the remaining features of flakes from an experimental assemblage. This assemblage was obtained by the expansion of a previous dataset through the inclusion of bigger flakes, allowing the analysis to account for the effects of sample size and value distribution. Correlation results show a large/ strong relation between predictions and real outcome (r 2 = 0.78 in the best case). Comparison of the models affords insights into variable importance for predicting flake mass. Results show that (for the present dataset) multiple linear regression still stands as the best method for predicting log of flake weight. Additionally, transformation of predicted values from the multiple linear regression and true values to the linear scale reinforces the linear correlation above the 0.8 threshold, This article is the result of the research projects “Como, Quien Y Donde?: Variabilidad De Comportamientos En La Captacion ´ Y Transformacion ´ De Los Recursos Liticos Dentro De Grupos Neandertales 2” (HAR2016-76760-C3-2-P) financed by Agencia Estatal de Investigacion ´ (AEI), Fondo Europeo de Desarrollo Regional (FEDER); and “En Los Limites De La Diversidad: Comportamiento Neandertal En El Centro Y Sur De La Penisula Iberica” (ID2019- 103987 GB-C33) financed by the Programa Estatal de Generacion ´ de Conocimiento y Fortalecimiento Científico y Tecnologico ´ del Sistema de I + D + i y de I + D + i Orientada a los Retos de la Sociedad, del Plan Estatal de Investigacion ´ Científica y T´ecnica y de Innovacion ´ (2017–2020).

Lithic assemblages immediately following the Howiesons Poort, often loosely referred to as the ‘post- Howiesons Poort’ or MSA III, have attracted relatively little attention when compared to other wellknown phases of the South African Middle Stone Age (MSA) sequence. Current evidence from sites occurring in widely-differing environments suggests that these assemblages are marked by temporal and technological variability, with few features in common other than the presence of unifacial points. Here we present a technological and geometric morphometric analysis of ‘points’ from the new excavations of Members 2 BS, 2WA and the top of 3 BS members at Border Cave, KwaZulu-Natal, one of the key sites for studying modern human cultural evolution. Our complementary methodologies demonstrate that, at this site, hominins adopted a knapping strategy that primarily produced non-standardised unretouched points. Triangular morphologies were manufactured using a variety of reduction strategies, of which the discoidal and Levallois recurrent centripetal methods produced distinctive morphologies. We find technological and morphological variability increases throughout the post-Howiesons Poort sequence, with clear differences between and within chrono-stratigraphic groups. Finally, we assess the suitability of the ‘Sibudan’ cultural-technological typology proposed for post-Howiesons Poort assemblages at Sibhudu, another KwaZulu-Natal site, and find similarities in the morphological axes characterising the samples, despite differences in the shaping strategies adopted. Overall, our work contributes to the growing body of research that is helping to address historical research biases that have slanted our understanding of cultural evolution during the MSA of southern Africa towards the Still Bay and Howiesons Poort technocomplexes., UK Research & Innovation (UKRI), Arts & Humanities Research Council (AHRC) NGS-54810R-19, Wenner Gren Foundation CEOOP2020-1, Poroulis grant through Cambridge University, Spanish FEDER/Ministry of Science and Innovation 262618, National Geographic Explorer grant ANR-10-LABX-52, DSI- NRF Centre of Excellence in Palaeosciences grant 191022_001, Research Council of Norway through its Centres of Excellence funding scheme, LaScArBx research programme, Grand Programme de Recherche 'Human Past' of the Initiative d'Excellence (IdEx) of the Bordeaux University, Leakey Foundation (Movement, interaction, and structure: modelling population networks and cultural diversity in the African Middle Stone Age), Lithic Studies Society (Jacobi Bursary Awardee, 2020), SFF Centre for Early Sapiens Behaviour (SapienCE), Talents Programme AH/R012792/1 Gr. 10157 PID2019-1049449 GB-I00

This paper presents the limestone reduction sequences documented in levels M and Ob at Abric Romaní from a technological point of view. At level M, a recurrent knapping system has been identified, resulting in the frequency of pseudo-Levallois blanks. At archaeolevel Ob, the presence of Levallois methods are observed in association with this knapping system. In both cases, retouched tools are rare and dominated by notches and denticulates. Although it is not well-known the degree of similarity and difference between the two levels in relation to occupational patterns is not well understood, Neanderthals employed more opportunistic knapping strategies, investing less time and energy in the procurement of raw materials including for chert. In level Ob, although limestone is still collected in the local fluvial deposits, differences in raw material procurement have been identified for chert. Results show the plasticity and versality that Neanderthals had and how they took advantage of the different abiotic resources they had around them. In this paper, we discuss the limestone technology at Abric Romaní in the context of the Iberian Peninsula., Research carried out for this paper has benefited from the following: “Síntesis del Paleolitico medio y superior en Valencia y Murcia: aspectos cronológicos, paleoambientales, económicos y culturales” (HAR2017-85153-P/MICINN), “El pasado lejano: aproximación a la conducta y la ocupación del territorio en el paleolítico valenciano” (PROMETEO/2017/060), “Neanderthal behaviour and paleoecology in Mediterranean ecosystems” (PID2019-103987GB-C31), “Redefiniendo forma, uso y expresión cultural en el Paleolítico medio” (SI1/PJI/2019-00488) and the Research Group nº 2017 SGR 836 of the Catalan Government.

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.

Gunflints represent a worldwide feature of lithic technology in modern times. This type of artefact was used to ignite the powder of firearms through a flintlock mechanismfrom the middle-seventeenth to the early-twentieth century in different contexts aroundthe world. Taking what is a novel and exploratory approach in historical archaeology, this paper offers a quantitative analysis of a random sample of 200 unused gunflints recovered from the British shipwreck Deltebre I. This cargo ship belonged to an alliedconvoy that unsuccessfully tried to liberate Tarragona city from the Napoleonic forces, and sunk in the Ebro river delta, Catalonia, Spain, in 1813. The results from size and shape characterisation of the unused gunflints using geometric morphometric methodsare presented. In order to assess morphometric variation between used and unused artefacts, this sample was compared with published images of 22 used British gunflints from different archaeological contexts. Finally, the usefulness of applied methodology to quantitatively characterise the design and morphometric variations of this kind of artefacts is highlighted. Fil: Ciarlo, Nicolás Carlos.

En las mesetas patagónicas existe una alta frecuencia de estructuras de piedra denominadas parapetos. El análisis de dichas estructuras y de los conjuntos tecnológicos asociados resulta relevante para abordar las características de la ocupación de estos espacios. Así, se busca evaluar la variabilidad de un conjunto de 11 parapetos del sitio Guitarra 10 (meseta del lago Guitarra, provincia de Santa Cruz, Argentina). El análisis comparativo del registro lítico es realizado desde dos aspectos. Por un lado, se focaliza en establecer las posibles diferencias en el uso del espacio interno y externo de las estructuras y por otro, se centra en dar cuenta de la variabilidad relacionada con la localización altitudinal de los parapetos dentro del sitio. Es esta última la que presenta un mayor aporte, permitiendo ampliar la discusión sobre las características de la utilización de estas estructuras.

Hafting is an important part of lithic technology that can increase our understanding of socioeconomic behavior in the past. In this article, we develop a holistic approach to studying hafting by using the concept of curation within a broader assessment of lithic technological organization in early villages. Early villages were loci of socioeconomic transformation as part of the shift from mobile foraging to more sedentary cultivation lifeways. We suggest that an examination of hafting can provide new insights into how early villagers negotiated technological requirements, economic decision making, and social interactions in these novel contexts. As a case study, we develop a curation index and apply it to an archaeological context of hafted and unhafted pointed tools from the early Neolithic village of Dhra’, Jordan. This curation index allows for a discussion of the technological, economic, and social dimensions of hafting strategies at Dhra’. The presence of multiple hafting traditions within early Neolithic villages of Southwest Asia is evidence of persistent social segmentation despite food storage and ritual practices that emphasized communal integration. Through the lens of lithic technological organization, we demonstrate that hafting and curation patterns can increase our understanding of technological, economic, and social strategies in early villages.

Loiyangalani is important to the understanding of human occupation patterns in the Serengeti and Northern Tanzania during the Middle Stone Age in terms of food-processing activities and lithic technology. The abundant faunal remains at the site show that it was used for game processing. The lithic technology was based on prepared core methods, dominated by the discoid and Levallois types, for the production of flakes. The retouched tools found at the site (scrapers, denticulates, and notches) are characteristic of activities associated with animal butchering while those connected with hunting activities are scarce. Some previous studies proposed that the Middle Stone Age occupation at Loiyangalani represents an independent industry in the region since the techno-typological differences noted between it and the neighboring sites are quite striking. We revisit this hypothesis by using three approaches—taphonomy, typology, and technology—for analyzing the MSA assemblage in Loiyangalani. We then compare the data from these three analyses with two other MSA industries in Northern Tanzania—Mumba and Nasera. Using principal component and cluster analyses to evaluate the typological and technological variation in these three industries, we show the patterns of differences and similarities among them and offer explanations for these patterns.

The Cradle of Humankind World Heritage site in South Africa is renowned for its karstic cave systems, which have yielded extensive fossil and stone tool assemblages dating to the Plio-Pleistocene period. The archaeological record from these caves has provided significant evidence for the evolution of lithic technology in southern Africa. Open-air sites have also been documented in this region, although they rarely receive scientific attention due to their lack of spatial and stratigraphic contexts. However, archaeological research has demonstrated that lithic production strategies were organized through landscape-scale constraints including the availability of raw materials and the energetic costs of their transport. As such, the study of open-air Stone Age sites in the Cradle of Humankind can potentially offer insight into the relationships between raw material procurement and reduction processes in this region. Here, we present a case study from the open-air locality of Elandsdrift Farm, which preserves a palimpsest of Earlier and Middle Stone Age lithic materials. While the chronological and spatial contexts of this locality present significant interpretative challenges, the Elandsdrift Farm lithic materials are not without scientific value. A landscape archaeological approach is employed to explore the influence of raw material transport on tool-making. Trends in core reduction intensity and flaking efficiency suggest that landform ruggedness and distances traveled to procure raw materials significantly influenced lithic production strategies throughout the Early to Middle Pleistocene. Despite the contextual challenges presented by open-air localities, landscape archaeological methods can inform the economic aspects of lithic scatters in this region, which cannot be easily inferred from archaeological assemblages in cave contexts.

Robert J. Patten passed away suddenly on February 8, 2017. His influence on flintknapping, lithic technology, and archaeology, however, continues on. Here, we review Patten’s life and myriad contributions.

This paper examines the archaeological case study of Miraflores rocks (tuff and silicified tuff) to explore several alternative causes of lithic transport in Fuego-Patagonia during the Late Holocene. Although these rocks are naturally available within a restricted area of northern Isla Grande of Tierra del Fuego, they were both transported several hundred kilometers away from the source in the Miraflores Valley, across and outside the island. Macroscopic, petrographic, and geochemical analyses showed that the identification of both raw materials isreliable, while an extensive sampling of Fuegian artifact collections has assessed the contribution of these rocks to the overall Fuegian lithic assemblages. The integration of technological data from extant Miraflores artifacts and the archaeological and ethnographic information available for Tierra del Fuego suggests that different factors conditioned the transport of Miraflores rocks.The initial goal of our studies was the silicified tuff; however, after ten years of work it appears that the major driving factor for exploitation at the Miraflores source area was the acquisition of tuff. Tuff would have offeredthe most adequate physical properties for the manufacture and use of large polishers with a variety of potential functions. Spatial analyses indicated that the cumulative distance of 200 km to the source (nearly 125 km in linear distance) probably represent the threshold of direct access to Miraflores. The distribution of Miraflores rocks beyond this radius involved other provisioning strategies. We conclude that most of the silicified tuff remains recovered at Fuegian sites represent incidental by-products of mobility, while tuff was an explicitly pursued material.

Rock art research carried out in the Strobel Plateau (Santa Cruz province, Patagonia, Argentina - 700 to 1200 masl) has shown that during Late Holocene population convergence took place in this area, where information was concentrated and distributed on a supra-regional scale (Belardi & Goni 2006; Goni 2010; Re 2010; Goni et al. 2007, 2014). The central position of this plateau in the province's steppe would also be a crucial factor regarding this process (Belardi & Goni 2006). In this context, the aim of this work is to study this idea of population dynamics given the evidence from lithic technology. In order to do this, we first consider the analysis of variability and provenance of lithic raw materials used for the manufacture of artefacts. It is important to highlight that after 15 years of research carried out in the Strobel Plateau we have not found any lithic source. However, previous works suggest that lithic resources used in the Strobel Plateau are located in nearby areas. Therefore, when analysing the variability, provenance and distance of sources, this work seeks to discuss the access to the plateau and the regional circulation axes. The obtained results support the idea of population convergence occurring in Late Holocene.

The apparent simplicity and the lack of changes in stone tool production during the Paleolithic in China is often explained by environmental, subsistence and demographic processes that either promoted a casual approach to lithic technological organization or impeded cultural innovation among East Asian hominin groups. This perspective stems from an assumption that complexity in lithic management is solely reflected in formalized core reduction methods, tool typology and/or the transport of non-local raw material types. In this study, by using survey to establish the baseline expectation of local raw material proportions, we demonstrate the differential treatments of locally abundant stone types at the Late Paleolithic site of Shuidonggou Locality 2. In spite of the apparent technological stasis, we observe shifting patterns of local raw material selection and transport during late Marine Isotope Stage 3. Hence our results suggest that, in basic core-and-flake assemblages, technological complexity is expressed in the selection, use and transport of lithic resources, including informal artifacts made on locally available raw material.

Recent research provides new perspectives on large-scale Early Holocene human interaction within Eurasia, based on ancient DNA or lithic technology. But the extent of regional human mobility is not well known. In this study, we combined two different approaches to investigate regional mobility and social networks in southern Scandinavia. We analyzed strontium isotopes in human teeth and regional lithic raw material use and technology from a Mesolithic site, Norje Sunnansund in southern Sweden (7000 BCE). The lithic raw material composition at the site, and previous archaeological studies, indicated that the inhabitants mainly had utilized an area stretching 30 km southward. The isotopic analysis indicated that at least half of the analyzed individuals had a non-local origin, based on the local isotope signature, but that possibly only a few individuals originated outside the area defined by lithic acquisition. Those few isotopic values and the presence of lithic material as non-local flint and East Swedish microblade-cores in quartz, suggested that people also traveled far, but probably more sporadically. The combined analyzes revealed the complexity of late Boreal hunter-gatherers in South Scandinavia – although some groups appear to have had a limited geographical mobility, contact networks seem to have stretched over long distances.
