The dissection of archaeological palimpsests has become a crucial process for achieving a diachronic understanding of the history of human groups. However, its widespread application to archaeological deposits has been hampered by both methodological and theoretical limitations, as well as by the inherent characteristics of the deposits. This paper explores whether overcoming these barriers, both methodological and theoretical, truly represents a significant shift in understanding past human behaviour, thereby motivating the pursuit of shorter timescales. To this end, we have analysed the lithic assemblages of Unit Xb from the Neanderthal site of El Salt (Alcoi, Iberian Peninsula) focusing on lithic attributes and raw material analyses, enabling the definition of raw material units and refitting sets. Considering these variables, we have applied archaeostratigraphic and spatial analyses in order to generate units of analysis whose content is compared to that of the entire unit. The defined archaeostratigraphic units display different spatial distributions and lithic composition. Some of them are attached to certain hearths and composed of refitted sets, while other units are related to areas without combustion evidence and integrated with bigger and heavier single products. Through this approach, here, we show that reducing the spatiotemporal scale of the record helps to unravel behavioural variability, reducing interpretative errors implicit in the assemblage-as-a-whole approach. This highlights the role of temporal resolution in reconstructing site formation processes and challenges research perspectives that assert the unnecessary or impossible nature of palimpsest dissection.

Evidence acquired in the past years highlighted the high complexity of Neanderthal subsistence strategies in terms of the spectrum of exploited species (mammals, birds, aquatic resources). However, in many sites diet was mainly focused on the acquisition and processing of large and medium-sized ungulates. In these cases, the evaluation of killing profiles and skeletal frequencies has allowed to highlight behavioural variability among Mousterian populations living in different geographical areas. In the frame of these studies, zooarchaeology and taphonomy of the Middle Palaeolithic phases (MIS 4/MIS 3) from the external deposit of Grotta di Santa Croce (Apulia, southern Italy) are presented in this paper. Faunal assemblage is almost exclusively composed of horse and aurochs remains. The sample, which is not altered by carnivore activities, mainly consists of intensively fractured limb bone shafts and isolated teeth. Epiphyses, tarsal/carpal bones, and phalanges are quite rare, as well as unidentified spongy bone fragments. Analysis of tooth eruption and wear points to the exploitation of adult individuals, rather than juveniles and sub-adults. Body part profiles, as well as mortality ones point to a specific hunting behaviour that may reflect particular nutritional needs. The hypothesis of an intense exploitation of fats is discussed.

In order to gain better understanding of the Neanderthals' subsistence exploitation of marine crustaceans, this work presents evidence on the consumption of brown crabs using experimentation following-up from the archaeological evidence recovered from the 2010-2013 excavation of Gruta da Figueira Brava (Portugal). Amongst the aquatic fauna from occupation phase FB4, which dates to MIS-5b, brown crabs (Cancer pagurus) are numerous. The average carapace width estimated from their remains is 16 cm, and skeletal part analysis reveals the introduction of complete animals and their on-site processing. Due to the lack of a referential corpus for the interpretation of archaeological crab taphonomy, we experimented with the processing of two raw, two boiled, and two roasted brown crabs. We found that manual processing of large adult Cancer pagurus is only possible for the disarticulation of the walking legs, and the separation of the claws. Experimental results indicate that archaeological crabs were roasted, which weakened the shell and facilitated breaking it open. Though it is also possible to manually disarticulate the fingers, most times it requires a small hammerstone. Impact scars and longitudinal fractures bear witness to the use of such tools to access the meatier parts of both the propodus and the dactylopodus. [ABSTRACT FROM AUTHOR]

Although the first numerical dating of Middle and Upper Palaeolithic sites in Poland was applied at the beginning of the second half of the 20th century, it has only been in the last two decades that a data increase has been recorded, making it possible to discuss both the development of human behaviour and cultural phenomena in time perspective. This paper aims to show the chronological diversity of sites dating from the beginning of the Weichselian glaciation (MIS 5a - MIS 5d, GI-19 - GI-23, Greenland Interstadials) to the middle part of MIS 3 (GI-8 - GI-10). We considered sites dated mainly by thermoluminescence dating (OSL) and radiocarbon dating. We relied on a series of recent datings. We attempted to analyse the stratigraphic integrity, the archaeological finds and the numerical dating results. Through OSL dating, we could establish the chronology of Micoquian sites, previously regarded as middle Pleistocene, to the last glaciation. The dating compilation also shows that the Late Middle Palaeolithic and Early Upper Palaeolithic (EUP) sites are unlikely to overlap, or if they do, it is only over a small period. Unfortunately, this period is poorly interpreted because it spans the limit of the radiocarbon dating reliability and goes beyond the bounds of the calibration curve. Confronting the datings of the Lincombian-Ranisian-Jerzmanowician (LRJ) complex and the oldest finds associated with Aurigniacian sites in Poland lead to the conclusion that these sites may have co-occurred for some time.

Horse tooth retouchers have been identified in several Middle and Upper Palaeolithic sites. They have been typically characterised as 'soft' hammers and/or grouped into the category of 'bone retouchers' at a technical level. Bone and teeth have different chemical compositions; teeth are denser and heavier than bone, and consequently, their technological features should not be considered homologous. In this work, we experimentally tested the effectiveness of horse teeth as retouchers. To perform this study, we used 41 modern horse teeth to shape flakes of various raw materials by applying different techniques. The resulting use-wear traces were analysed using high-resolution methods and then characterised. The results allowed us to identify the effectiveness of hypsodont teeth in knapping a wide range of tools and to evaluate the influence of 1) the raw materials, 2) the retouching techniques and 3) the gestures of the different knappers on the morphology of the use-wear marks. This work sheds light on the purpose of using teeth as tools by both Neanderthal and early modern human populations as well as understanding how these human species used them. The study leads us to consider tooth retouchers as important elements of the chaîne opératoire in lithic manufacture. Our goal is to highlight the importance of these types of experimental studies to create analogies and infer past processes. [ABSTRACT FROM AUTHOR]

Bone retouchers, while often underrated, stand out as widespread tools throughout the Palaeolithic, typically linked to breaking bones for marrow extraction. Although bone retouchers are commonly considered a by-product of butchering activities, the possibility of intentional manufacturing has been rarely considered but should not be dismissed. In our experimental protocol, we explore decision-making processes involved in manufacturing bone retouchers, focusing on how these decisions are guided by intentional production rather than solely marrow extraction. The results indicate that individuals employ specific techniques and make technological decisions, rapidly acquiring experience in retoucher manufacturing that extends beyond mere intuition. The choice of bone-breaking technique(s) reflects the intention behind either marrow extraction or producing suitable bone fragments for retouchers. This decision-making process is heavily influenced by the morphology of the bone, presenting challenges that individuals learn to overcome during the experiment. The analysis of the experimental percussion marks suggests that certain marks on specific skeletal elements indicate intentional bone retoucher manufacturing. We then propose a likelihood grid to assess the reliability of traces on each skeletal element in inferring intentional manufacturing. Given the abundance of bone retouchers in Middle Palaeolithic contexts, a thorough investigation into the intentionality behind their manufacturing processes could significantly impact their relevance within other Palaeolithic bone industries.

The Middle Stone Age in northwest Africa is mainly described in terms of two technocomplexes, the Aterian and Mousterian, the definitions of which have evolved as research has progressed. While the Aterian is often characterised by tanged tool assemblages, the Mousterian seems to have been defined by default and other denominations such as Levalloisian, Middle Palaeolithic and Sbaikian have also been used for MSA lithic assemblages without pedunculates. Beyond the legitimate question of the relevance of these classifications, one may wonder whether the available quantitative data allow us to identify the variability of lithic assemblages outside the Aterian technocomplex. In the Algerian context, this question is addressed by analysing data recovered by researchers from archaeological sites qualified as non-Aterian. Information and gaps are discussed and compared with what is known about the same period in northwestern Africa, particularly Morocco. [ABSTRACT FROM AUTHOR]

Bawa Yawan Rock Shelter is one of the critical Palaeolithic sites discovered recently in the Central Zagros in Western Iran. The site exhibits a rich assemblage from the Middle Palaeolithic (Zagros Mousterian) to the Epipalaeolithic, and it discloses one Neanderthal canine tooth. The site stands out as one of the handfuls of Palaeolithic sites in the Central Zagros that contain human remains. Therefore, establishing a reliable chronology revealing the temporal period in which Neanderthals inhabited the region plays a significant role in our understanding of the human past in the region. We employed luminescence dating in combination with Bayesian modelling to improve the precision of the estimated ages. Our results indicate that the Middle Palaeolithic assemblages unearthed from geological layers GH3 to GH5 in the site fall in the [58–80] ka time frame (68% credible interval). More importantly, the Bayesian age for the layer containing the Neanderthal remains exhibited [65–71] ka (68%). This age contradicts the previous 14C-based chronology. We argue that it is likely that the 14C dates underestimate the timing of the Middle Palaeolithic industries at Bawa Yawan. Furthermore, our study reveals the first luminescence age for the Epipalaeolithic in the Central Zagros, which is dated to [13–15] ka (68%). [ABSTRACT FROM AUTHOR]

Buena Pinta Cave (Pinilla del Valle, Madrid) has been interpreted as a hyena den with sporadic occupations of Homo neanderthalensis in the western part of the site (level 23). In order to identify the different formation processes in this area of the site, spatial analyses have been carried out with GIS and spatial statistics based on the taphonomic analysis of the faunal remains. Based on the vertical and sectional analyses of the assemblage, it has been possible to determine that level 23 actually corresponds to three archaeological levels with well-differentiated characteristics: a lower level with few faunal remains and fossil-diagenetic alterations related to humid environments associated with clays; an intermediate level with a high percentage of remains with water-related modifications and evidences of transport; and an upper level delimited mainly thanks to by a paraconformity evidenced by the concentration of weathered remains in this area and a significant reduction in remains with water-related alterations above. The results obtained show the necessity to redefine field layers and the usefulness of integrating taphonomic data and spatial studies. [ABSTRACT FROM AUTHOR]

The discovery of a very distinct and rather isolated group of the Middle to Early Upper Palaeolithic sites around the Svitava River to the north of Brno has been made very late. This study focuses on the new collections assembled by Petr Gadas and comprising all groups of artefacts. The Horky Hill above Bořitov was the site of one of the biggest centers of the Middle Palaeolithic Micoquian. Despite the presence of one of the Cretaceous spongolite (i.e., the most numerous raw material) outcrops directly on the hillside this was not a workshop site; the quantity of retouched tools even outnumbers the contents of all the Middle Palaeolithic levels in the Kůlna Cave altogether. Both sites fundamentally differ in a much stronger representation of prismatic cores, blades, and characteristic Upper Palaeolithic types at Bořitov V; the dominant hill certainly draw attention even after the demise of the Micoquian. However, the degree of patination is identical in all types of cores and tools. A part of progressive elements in the sphere of technology (blades and blade cores) and typology (end scrapers, often with pronounced side retouch) can occur even in the late phase of the Micoquian, perhaps the main period of occupation of the site.

Nubian Levallois technology has become a prominent and hotly debated topic in current Palaeolithic discourse, with important arguments surrounding modern human dispersals, cultural interactions and technological innovations resting on the presence of Nubian cores in lithic assemblages. However, not all published instances of Nubian cores fulfil their strict technological criteria, with resultant implications for how their presence in space and time is interpreted. To address this, this dataset compiles a comprehensive literature review of 154 published sites where Nubian cores have been reported. Each case is presented with key contextual information synthesised from the literature, and the identification of Nubian cores is critically evaluated. The dataset shows that over the last decade, while there has been a marked increase in the number and distribution of sites with reported Nubian cores, these artefacts increasingly diverge from the technological and morphological characteristics that define this core type. As such, 24 identifications are queried as not fulfilling the strict Nubian core criteria. A further three are rejected with no supporting evidence in the literature, and four noted as contested cases. This dataset serves as a key resource for studies of Nubian Levallois technology, providing a centralised literature review with spatial and contextual data to support robust future research on the topic.

Archaeological and palaeoenvironmental evidence from the Armenian Highlands and wider southern Caucasus region emphasises the significance of Marine Oxygen Isotope Stage 3 (c. 57–29 ka) as a crucial period for understanding hominin behaviours amidst environmental fluctuations. Ararat-1 cave, situated in the Ararat Depression, Republic of Armenia, presents potential for resolving emerging key debates regarding hominin land use adaptations during this interval, due to its well-preserved lithic artefacts and faunal assemblages. We present the first results of combined sedimentological, geochronological (luminescence and radiocarbon), archaeological and palaeoecological (macrofauna, microfauna and microcharcoal) study of the Ararat-1 sequence. We demonstrate sediment accumulation occurred between 52 and 35 ka and was caused by a combination of aeolian activity, cave rockfall and water action. Whilst the upper strata of the Ararat-1 sequence experienced post-depositional disturbance due to faunal and anthropogenic processes, the lower strata remain relatively undisturbed. We suggest that during a stable period within MIS 3, Ararat-1 was inhabited by Middle Palaeolithic hominins amidst a mosaic of semi-arid shrub, grassland, and temperate woodland ecosystems. These hominins utilised local and distant toolstone raw materials, indicating their ability to adapt to diverse ecological and elevation gradients. Through comparison of Ararat-1 with other sequences in the region, we highlight the spatial variability of MIS 3 environments and its on hominin land use adaptations. This demonstrates the importance of the Armenian Highlands for understanding regional MP settlement dynamics during a critical period of hominin dispersals and evolution.

The chronology and hominin association of the South Asian Middle Palaeolithic have attracted much attention in the last few decades. The emergence of Middle Palaeolithic culture in the region has been debated between the local origins (behavioural change) model based on an early date around 380 ka and the diffusion (biological change) model based on Homo sapiens dispersals from Africa around 120-80 ka. The latter has more consensus, whereas the former requires a more robust chronological framework to attribute the emergence of the Middle Palaeolithic to behavioural changes. In the absence of hominin remains, the presence of Middle Palaeolithic technological trajectories are frequently used as behavioural markers of Homo sapiens. Homo sapiens fossil remains from the regions between Africa and South Asia dated to ~ 200 ka presents more convincing support for the latter model. Here we present contextual, chronological and technological analysis of Middle Palaeolithic assemblages dated to 52 ka from Motravulapadu, Andhra Pradesh, India. Morphometrical analysis of the lithic assemblage indicates diverse Levallois core reductions were practised at the site at the onset of MIS 3. Further this evidence highlights the significance of MIS 3 cultural diversity in South Asia, likely related to changing population dynamics, cultural drift, and the highly variable climatic context of MIS 3.

This research is helping to understand the role of the hyena in the origin and accumulation history of the site of Érd's bone assemblage, in which the role of Neanderthals is also clearly highlighted. It attempts to provide an insight into the destructive potential of this carnivore at Érd and in the corpus of Hungarian sites. [ABSTRACT FROM AUTHOR]

Bone retouchers are a technological appliance used to perfect lithic tools efficiently. They are most frequently found in Middle Palaeolithic contexts. In this paper, we present a group of bone retouchers from the Mousterian Level XV of the Sopeña rock shelter (Asturias, Spain). The bone part preferred was the middle part of the shaft of long bones: Most of them are on metacarpals, followed by metatarsals, femurs, and tibias. The most used animal species is adult red deer. These retouchers have either one, two, or three active areas, with a central disposition. The impact marks are close together; oval pits are common, as well as straight, sinuous, and irregular grooves. The surfaces on these marks appear pitted and scaled. There are indications that the bones employed were relatively fresh. The length, width, and thickness of those bone fragments seem to be the determining factor when choosing them to be used as retouchers in the process of finishing lithic tools. The formats documented in Sopeña Level XV are similar to those found in other Mousterian sites in Iberia, although there is a certain variability regarding their width. The Neanderthals of Sopeña acquired the raw material for these retouchers from the faunal remains generated in the process of butchering and eating the animals. These retouchers were used as implements to perfect lithic tools made mainly on quartzite, and they were used repeatedly and maybe for a long time. [ABSTRACT FROM AUTHOR]

The Abrigo de la Quebrada is a Middle Palaeolithic rockshelter located in the Rambla de Ahíllas in the Iberian Range (Valencia, Spain). Archaeological work began in 2007 and was completed in 2015, reaching the rockshelter substratum and uncovering a record that spans from MIS 5 to MIS 4/3. The data from the geoarchaeological and micromorphological study of the site allow us to deduce that it was formed by alluvial contributions from the ephemeral stream, in different subenvironments varying from channel/bar to floodplain facies. These alternate with debris from different displacement processes depending on the unit, such as solifluction–gelifluction, mass displacement, and diffuse runoff. In addition, collapse episodes of the overhanging rockshelter roof influenced the pedological evolution of the record, with implications for the archaeological levels, especially in Unit G (Level IV). From a paleoenvironmental point of view, a more contrasted variability is reflected in the upper units of the site (MIS 4/3), especially in Unit G (Level IV), which, based on data, suggests temperate conditions, and in Unit H (Levels III and II) indicate cold conditions. In contrast, the lower units (MIS 5) are generally temperate, with the exception of Unit C (Level VIIIa), which reflects a colder phase. [ABSTRACT FROM AUTHOR]

During the last glacial period, rapidly changing environments posed substantial challenges to Neanderthal populations in Europe. Southern continental regions, such as Iberia, have been proposed as important climatic "buffer" zones during glacial phases. Contextualising the climatic and ecological conditions Neanderthals faced is relevant to interpreting their resilience. However, records of the environments and ecosystems they exploited across Iberia exhibit temporal and spatial gaps in coverage. Here we provide new evidence for palaeotemperatures, vegetation structure, and prey herbivore ecology during the late Pleistocene (MIS 5-3) in northern Spain, by applying multiple stable isotope tracers (δ18O, δ13C, δ15N, δ34S) to herbivore skeletal remains associated with Neanderthal occupations at Axlor Cave, Bizkaia. The results show little change over time and indicate stable climatic conditions and ecosystems across different occupations. Large within-layer isotopic variability in nitrogen and sulphur suggests the presence of a mosaic environment and a variety of isotopic ecotones that were exploited by Neanderthals and their prey. We implement a combination of carbonate and phosphate δ18O measurements to estimate palaeotemperatures using a cost-effective workflow. We show that the targeted use of phosphate δ18O measurements to anchor summer peak and winter trough areas enables high-precision seasonal palaeoclimatic reconstructions. [ABSTRACT FROM AUTHOR]

The extinction of Neanderthal populations has been attributed to the onset of cold and dry climatic conditions during Marine Isotope Stage 3 or their competition with anatomically modern humans for large game resources. However, decoupling climate from competition has long proved difficult. Loess sequences and pollen cores provide regional‐scale environmental information but are less well‐suited to providing local‐scale habitat information contemporaneous with hominin habitation of occupation sites. The relationship between climate and resource availability is particularly unknown in the Zagros mountain range where archaeological evidence for both Neanderthals and Homo sapiens occupation is documented. Here, we analyse carbon (δ13C) and oxygen (δ18O) stable isotopes measured from herbivore tooth enamel carbonates recovered from the Neanderthal and modern human occupation sites of Bawa Yawan Rockshelter and Shanidar Cave to trace local‐scale floral biome dynamics and climate conditions that influence the distribution and availability of large prey targeted by both hominin species. Shared isotopic composition of herbivorous fauna, largely represented by wild goats, from both sites spanning Neanderthal and Homo sapiens occupation indicate both hominin species exploited similar habitats during climatically similar phases.

The cave site of Axlor (Biscay, Spain) preserves one of the most informative Middle Palaeolithic (MP) records for the North Atlantic Iberian region, though its age remains poorly known. Here we use single‐grain optically stimulated luminescence (OSL) and single‐grain thermally transferred OSL (TT‐OSL) dating of sediments to improve the age constraint of Axlor's MP succession (levels N–B). Our new ages are consistent with the previously published terminus ante quem14C ages for the site (>42.9 cal ka bp), and suggest the sequence accumulated during a period of ~50 kyr. Axlor's levels N–F were deposited ~100–80 ka, probably during marine isotope stage (MIS) 5d–a, while levels D and B were deposited ~70 and ~50 ka, respectively, during MIS 4 and mid‐MIS 3. Our results indicate that major faunal and technological turnovers occurred towards the end of MIS 5, potentially coinciding with broader environmental and climatic changes. Axlor's Quina record, dated here to the onset of MIS 4, is one of the oldest in Europe. Comparisons with neighbouring sites point to complex regional chronologies and development for this particular behaviour, though detailed correlations with other MP sequences remain difficult due to their poor chronological attributes. The present study highlights the important role that single‐grain optical dating can play in elucidating the broader evolution of the MP across southwestern Europe. [ABSTRACT FROM AUTHOR]

During the summer of 2019, the Bacton to Walcott Coastal Management Scheme involved the emplacement on to the foreshore of 1.8 million cubic metres of sand and gravel dredged from the submerged sediments of the Palaeo‐Yare in the southern North Sea 11 km off Great Yarmouth. During the following 2‐year period, an active group of collectors identified Palaeolithic artefacts eroding from these sediments, including Levallois cores and flakes, and cordiform handaxes. In this paper, we present an analysis of the lithic artefacts, and consider the relationships between the different elements of the assemblage. We discuss its significance in the context of the Middle Palaeolithic record of northwest Europe and the light it shines on the human occupation of the submerged landscape of the southern North Sea during the later Middle Pleistocene. Interrogation of beach survey data shows the reworking of these sediments to the southeast towards Happisburgh where archaeologically significant exposures of the Cromer Forest‐bed Formation are located. The implications of the introduction of a Middle Palaeolithic assemblage to this stretch of the North Norfolk Coast are considered, highlighting the importance of continuing dialogue between researchers, local authorities and local communities for capturing information and monitoring this critical Palaeolithic resource.

Use-wear analyses are very useful to increase knowledge about the economic and subsistence dynamics carried out by Neanderthals. In general terms, functional results traditionally came from the analysis of tools belonging to stratigraphic units whose timescale refers to geological time. This is due to the fact that many Neanderthal sites are palimpsests of reiterated occupations over time, which must be dissected to approach us to human timescale. In the stratigraphic unit xa of El Salt (Alcoi, eastern Iberia), high temporal resolution archaeostratigraphic studies have been carried out. Diachronic material assemblages have been identified, allowing us to analyse more precisely the variability of Neanderthal behaviour over time. Amongst these assemblages, three have been selected (i.e. 5.3.1, 5.3.2 and 5.3.3) in order to analyse the lithic material functionality. The results obtained bring out the performance of different tasks within each analytical framework: woodworking in 5.3.1, woodworking and animal processing in 5.3.2, and butchering activity in 5.3.3. These results reflect the existence of a series of diachronic tasks carried out in overlapping activity areas. In this way, this work evidences flint use variability in a specific area of the site across time that could have been recognised only by means of high temporal resolution analytical frameworks.

La Mina is one of three sites, along with Cueva Millán and La Ermita, located in the middle course of the Arlanza river. La Mina was excavated for the first time in 2006 and three test pits were carried out. In one of them, evidence of two Palaeolithic occupations was identified and several remains of woolly rhinoceros were recovered. Amino acid racemisation dating yielded an age of 52.5 ka BP, the earliest Upper Pleistocene date for Coelodonta antiquitatis on the Iberian Peninsula. This new record may have several implications for understanding the access routes to the Castilian Plateau, together with the definition of a new migratory wave of this species at the end of the Pleistocene. The location of La Mina on the Castilian Plateau may help researchers to complete the movements of this species through the Middle and Upper Palaeolithic on the Iberian Peninsula.

Pleistocene faunal assemblages are often highly fragmented, hindering taxonomic identifications and interpretive potentials. In this paper, we apply four different methodologies to morphologically unidentifiable bone fragments from the Neanderthal open‐air site of Salzgitter‐Lebenstedt (Germany). First, we recorded zooarchaeological attributes for all 1362 unidentifiable bones recovered in 1977. Second, we applied zooarchaeology by mass spectrometry (ZooMS) to 761 fragments, and calculated glutamine deamidation values. Third, we assessed the collagen preservation of 30 fragments by near‐infrared spectroscopy (NIR) and, finally, we pretreated 10 bones with high predicted collagen values for radiocarbon dating. All returned dates at, or beyond, the limit of radiocarbon dating, indicating an age of older than 51 000 years ago. The ZooMS faunal spectrum confirms a cold environment, dominated by reindeer, alongside mammoth, horse and bison. The low occurrence of carnivore modifications (1%) contrasts with an abundance of human modifications (23%). Cut marks and marrow fractures were observed across reindeer, horse and bison. The mammoth remains are less well preserved and show a lower degree of human modifications, indicating, perhaps, a different taphonomic history. Overall, this study illustrates the importance of retaining, studying and incorporating the unidentifiable bone fraction to optimize interpretations of site formation and subsistence behaviour at Palaeolithic sites.

Until recently, evidence of Neanderthal cave use in the Algarve (Southern Portugal) came only from the site of Ibn Ammar. Over the last couple of years, archaeological excavations inside another cave, Gruta da Companheira, yielded Mousterian stone tools associated with possible human fossils. The discovery of this assemblage is groundbreaking because it may contribute to enlighten the Neanderthal/cave relationship and explain the dearth of similar sites in the Algarve. Gruta da Companheira, however, is a complex karst system, which was partly destroyed during its accidental discovery. As result, the original entrance of the cave remains unknown, and it is unclear how sediments, archaeological materials and Neanderthals accessed the site. To tackle these issues, we combined geomorphological observations with speleological, Electrical Resistivity Tomography (ERT) and Ground‐Penetrating Radar (GPR) prospections. Our data indicate that Gruta da Companheira was probably accessed from the hilltop through a sub‐vertical entrance. Additionally, our results suggest the existence of yet unexplored shallower cavities connected with the already known passages of Gruta da Companheira. These results will guide the opening of new excavation areas at the site. The limestone bedrock hosting Gruta da Companheira has been extensively dissolved by karst processes. Therefore, it is necessary to focus future research on the cave infillings to clarify whether Neanderthals exploited the cave's inner chambers or alternatively limited their occupations to the hilltop and geogenic processes reworked their materials into the endokarst system shortly after their stays. The deep karstification and partial collapse of the hill hosting Gruta da Companheira are common in limestone outcrops that occur throughout the Western Algarve. Poor visibility and poor accessibility of this karst area, densely covered with shrubby vegetation, are factors that need to be considered when addressing the scarcity of Middle Palaeolithic cave sites in this region.

Spatial analysis has been much used to examine the distribution of archaeological remains at Pleistocene sites. However, little is known about the distribution patterns at sites identified as hunting camps, i.e., places occupied over multiple short periods for the capture of animals later transported to a base camp. The present work examines a Neanderthal hunting camp (the Navalmaíllo Rock Shelter in Pinilla del Valle, Madrid, Spain) to determine whether different activities were undertaken in different areas of the site. A spatial pattern was detected with a main cluster of materials (lithic tools, faunal remains, and coprolites) clearly related to the presence of nearby hearths—the backbone of the utilised space. This main cluster appears to have been related to collaborative and repetitive activities undertaken by the hunting parties that used the site. Spatial analysis also detected a small, isolated area perhaps related to carcasses processing at some point in time and another slightly altered by water. [ABSTRACT FROM AUTHOR]

The hunting activities of Neanderthals inhabiting the European Lowlands during the Weichsel glaciation are poorly understood due to the scarcity of faunal remains. This work concerns the puzzling accumulation of mammalian remains at the Middle Palaeolithic site Haller Av. in Wrocław, southwestern Poland. The site yielded lithic artifacts in two levels and numerous bone remains typical for steppe-tundra fauna, dominated by steppe bison (Bison priscus). As the site was transformed by fluvial processes, the question arose whether the accumulation of faunal bones was the result of human activity. To resolve this question, we used a multiproxy approach, including spatial analysis with GIS, as well as taphonomic and paleozoological analyses. It was found that the accumulation of bone remains was multi-stage and involved a large area. Only the bison remains were spatially correlated with the traces of human activity. In our opinion, these data indicate the presence of a hunting site of monospecific fauna, demonstrating the profound knowledge of Neanderthals about the ecosystem of which they were a part.

Data about Palaeolithic peopling, settlement dynamics and techno-economy of the south-western margin of the Alpine region are sketchy. In this area, the lack of systematic research and the scarcity of lithic raw materials, spread the idea that Piedmont was not inhabited during Palaeolithic. In 2009, the re-starting of the excavations at the Ciota Ciara cave, gave rise to new questions and to the development of research projects at a regional scale. The Ciota Ciara cave is the only Middle Palaeolithic site object of multidisciplinary and systematic investigations. Its lithic assemblage, analysed through a techno-economic approach, allows to understand in detail the technological choices and the land mobility of the Neanderthal groups on a local and sub-regional scale. Other Middle Palaeolithic assemblages are known in the region and are all issued from surface collections. They come from the northern part of the region, from Vaude Canavesane, Trino, Baragge biellesi and Colline Novaresi. The technological study of these assemblages led to the identification of strong similarities in the technological choices of the Middle Palaeolithic human groups: they based their technology on the exploitation of vein quartz, a rock diffused all over the regional territory, from time to time accompanied by other local (spongolite, rhyolite, metamorphic rocks, jasper) and allochthonous (radiolarite and flint) lithic resources, with technological adaptation to their quality and mechanical properties both when it comes to predetermined methods (Levallois and discoid) and when expedient reduction sequences are used. Concerning Upper Palaeolithic, the only lithic assemblage issued from an archaeological excavation (and therefore with a clear stratigraphic context) is that from the Epigravettian site of Castelletto Ticino. Other lithic artefacts referable on a techno-typological basis to Upper Palaeolithic are from Trino and Colline Novaresi. As for Middle Palaeolithic, the techno-economic approach used in the analysis of these lithic assemblages, allow to have, for the first time, reliable data at a regional scale. In this work we present the data obtained after about ten years of research in Piedmont: they outline a scenario where, even in the limits of analysis mostly based on materials issued from surface collections, we can see both clear differences between the Middle and the Upper Palaeolithic technological behaviours and hypothesise the land mobility of the hunter-gatherers’ groups that inhabited the region.

Lithic artefacts are usually associated with the different knapping methods used in their production. Flakes exhibit metric and technological features representative of the flaking method used to detach them. However, lithic production is a dynamic process in which discrete methods can be blurred, and in which features can vary throughout the process. An intermediate knapping method between the discoid and Levallois is commonly referred to under an umbrella of terms (the present research uses the term hierarchical discoid), and is associated with a broad geographical and chronological distribution throughout the Early and Middle Palaeolithic. This intermediate knapping strategy exhibits features of both the discoid and Levallois knapping methods, raising the question of the extent to which flakes from the three knapping methods can be differentiated and, when one is mistaken for another, the direction of confusion. An experimental assemblage of flakes detached by means of the three methods was used along with an attribute analysis and machine learning models in an effort to identify the knapping methods employed. In general, our results were able to very effectively differentiate between the three knapping methods when a support vector machine with polynomial kernel was used. Our results also underscored the singularity of flakes detached by means of Levallois reduction sequences, which yielded outstanding identification values, and were rarely erroneously attributed to either of the other two knapping methods studied. Mistaking the products of the discoid and hierarchical discoid methods was the most common direction of confusion, although a good identification value was achieved for discoid flakes and an acceptable value for hierarchical discoid flakes. This shows the potential applicability of machine learning models in combination with attribute analysis for the identification of these knapping methods among flakes.

The Mediterranean basin constitutes one of the best areas to analyse Neanderthal populations and lifestyles in South-Western Europe. In this context, new excavations conducted in the Middle Palaeolithic site of Cova del Puntal del Gat expand the information available regarding this rich region. In this study, new results are reported, including detailed studies on stratigraphy, lithic technology, anthracology, carpology, and zooarchaeology and taphonomy of macro and micromammals, with the final objective of characterizing the Neanderthals’ subsistence strategies and occupational patterns. These results are framed within a broader regional study perspective that includes MIS 5 and 4 sites. Chronostratigraphic review has enabled us to reorganize many sites that were originally included in MIS 3, towards older stages belonging to the end of MIS 4 and throughout MIS 5.

Although intra-site spatial approaches are considered a key factor when interpreting archaeological assemblages, these are often based on descriptive, qualitative, and subjective observations. Currently, within the framework of research into spatial taphonomy and palimpsest dissection, several studies have begun to employ more quantitative and objective techniques, implementing tools such as geostatistics and geographic information system (GIS) methods. This is precisely the approach that the Abric Romaní team is following. In this work, we present GIS and geostatistics methods applied to the faunal and lithic assemblages from archaeolevel Ob, including an analysis of the spatial structure, the identification of clusters and sectors, size and fabric analyses, the projection of vertical profiles, and the reconstruction of a digital elevation model of the paleosurface. The results obtained indicate a clustered distribution, primarily concentrated into four dense accumulations. The predominance of remains < 3 cm in length and the absence of preferential orientations make it possible to rule out a generalised postdepositional movement affecting most of the site, although some local movement has been identified. The horizontal and vertical spatial analyses allow us to identify accumulations of a single material (lithic or faunal) in addition to mixed accumulations (lithic and faunal). Integrating all this data with the results of previous studies (zooarchaeological, refits, combustion structures, and partial lithic technological analyses), we evaluate and combine the interpretations proposed previously using different approaches, thereby improving the overall interpretation of the archaeolevel Ob. Finally, we also develop a preliminary comparison between Ob and some other levels at the same site (in particular M and P). [ABSTRACT FROM AUTHOR]

Our paper presents new information regarding the site of Cheia – La Izvor. New radiocarbon ages were obtained, and they confirm that the occupation was at around 36 ka BP (ca. 40 ka cal BP). The faunal analysis has revealed that the cave seems to have functioned as a shelter for carnivores, with the remains of cave bear predominating. Other carnivores, such as cave hyenas, wolves and foxes, most likely also contributed to the accumulation of bones, with large, middle and small prey species represented. No anthropogenic traces were identified on the bones. The very small lithic collection comprises mostly formal tools, thus accounting for a short-term, logistic occupation of the site.

Zooarchaeological analysis is a useful means of exploring faunal palaeoecology, paleoclimate and past human behaviours. The Middle Pleistocene archaeological site Lazaret Cave, located in modern-day Nice, France, features a vast assemblage of faunal remains pertinent to the understanding of early Neanderthal subsistence behaviours as well as red deer (Cervus elaphus) ecology during MIS 6. This pilot study examines materials from archaeological layer UA25, a short-term occupation layer at Lazaret dating to ~150,000 years ka, which has revealed 28 early Neanderthal remains as well as thousands of faunal bones, of which red deer and ibex (Capra ibex) are most abundant. Molars from three red deer mandibles and a single ibex were analysed for strontium (87Sr/86Sr) isotopic analysis using laser ablation mass spectrometry to determine animal movements during tooth formation, combined with intra-tooth oxygen (δ18O) isotope analysis to determine seasonality. The isotope data was modelled within a local 87Sr/86Sr isoscape and computational spatial assignment was undertaken to reconstruct potential summer and winter ranges of red deer. Results from this pilot study show seasonal mobility within 20 km of Lazaret, identifying two possible summer and winter ranges for the red deer excavated from UA25. Both possible summer ranges are located at higher elevations further from Lazaret while winter ranges have been assigned to lower elevations closer to the coastline and closer to Lazaret. The ibex shows no 87Sr/86Sr variation throughout the first, second and third molar and the spatial assignment indicates it lived proximal to the site during the period of tooth formation. In addition to providing the first evidence of red deer spatial ecology in southern France during MIS 6, we also infer from the faunal isotope data that hominins at Lazaret Cave were likely hunting red deer in autumn and winter when they were closer to the cave site, while hunting in summer would have required up to 20 km of travel.

Accomplishing long-term plans to harvest and modify natural resources has been a crucial skill for the survival of our species since early Prehistory. Research on this first step of production mostly focuses on the provenience study of lithic artifacts uncovered at archaeological sites, using petrographic and geochemical analyses to correlate the artifacts with potential geological outcrops. Although fundamental for understanding key aspects of landscape use and mobility, regional raw material economy, and extraction technology, Palaeolithic raw material sources have been less intensively investigated, as they are often difficult to locate and challenging to tackle with traditional archaeological approaches. Lojanik in the Central Balkans is one of the largest Prehistoric quarrying areas known in Europe, showing numerous lithic raw material outcrops exploited from the Middle Palaeolithic to the Chalcolithic periods, over an area of 18 hectares. In this paper, we present the results from our renewed research program in this region. Combining airborne LIDAR mapping, geomorphological and archaeological survey, and techno-typological analysis of lithic artifacts, we were able to reconstruct the geomorphological evolution of the landscape and its use by prehistoric societies.
