Iberia, a natural cul-de-sac peninsula, plays a major role in the study of the Neanderthals demise and its eventual relationship with the spread of Anatomically Modern Humans (AMH) in Europe. The site of Cova Eirós (Galicia, Spain), located in NW Iberia, contains Middle and Upper Palaeolithic levels, based on the cultural remains recovered at the site. No human remains directly associated with those levels were discovered yet. The available radiocarbon dates from the levels 2 (c. 35 ka cal BP, Early Upper Paleolithic) and 3 (c. 41 ka cal BP, Late Middle Paleolithic), point to a late survival of Neanderthal groups in North Iberia and to a relative quick arrival of the AMH, c. 35-36 ka cal BP, with respect to other territories of the Iberian Peninsula. The archaeological record shows clear differences between the Middle and the Upper Palaeolithic occupations, regarding raw-material acquisition, lithic technology and subsistence strategies. The location of Cova Eirós in the westernmost margin of the Cantabrian Rim and in the Atlantic Façade, makes this site a key place to understand the spread of the first AMH and the progressive demise of Neanderthal populations.

The comparative assessment of dietary choices as part of landscape use strategies deployed by Neanderthal and Anatomically Modern Human populations in Eurasia constitutes a fundamental avenue of Palaeolithic research. The increasing number of taphonomic assessments enables a better understanding of what remains were brought to sites by human hunters versus mammalian carnivores or raptors. A zooarchaeological approach can further elucidate the spatio-temporal dynamics of interaction between carnivores and human populations in terms of landscape use and prey choice during this transitional period. To achieve this objective, we conducted an examination of zooarchaeological and taphonomic data, carnivore indices, and other relevant variables across 36 Middle and Early Upper Palaeolithic sites in northern Iberia. These sites encompass 126 archaeological layers dating from 50,000 to 30,000 years ago. Our comprehensive bibliographic meta-analysis reveals that human occupations by both groups at sites across the region were punctuated by episodes influenced by carnivores. This observation implies that human occupations in northern Iberia during Marine Isotope Stage 3 were generally characterised by instability and limited to short periods, often seasonal in nature. From a zooarchaeological perspective, the combined assessment of taxonomic data, species richness and assemblage diversity highlights that the range and proportion of species acquired by these different human groups are similar, although Anatomically Modern Humans engaged in a sustained trend towards increasing dietary diversification even at sites with assemblages heavily dominated by one taxon. • Debating Diets: Assessing the dietary ecology of Neanderthals and AMHs in ecologically analogous environments. • Holistic Approach: Relevant insights into the temporality of site occupation patterns during the MP-UP transition. • Human-Carnivore Interaction Dynamics in northern Iberia during MIS 3 were impacted by dynamic interaction with different carnivore species in the landscape. • Our methodology encompasses quantitative palaeoecological, taphonomic and statistical assessments.

This paper presents new archaeological material and first dates on Upper Pleistocene layers at the site of La Crouzade cave (Gruissan, Aude, France). The site was first excavated by T. and P. Héléna at the beginning of the twentieth century, and the excavations were recently completed during three years (2016–2018) of systematic campaigns. We obtained dates from Middle Palaeolithic layers using two methods: AMS 14C dates were obtained from bone and charcoal, and combined ESR-U series dating was undertaken on horse teeth. Together, these methods allowed us to date this Mousterian sequence to 49,776–44805 cal BP for the deepest level (layer C8) and from 42,000 ± 3000 years BP for the top (layer C6). The Upper Palaeolithic layers are preserved only as patches in the actual excavation area, but a date was obtained from a piece of charcoal collected from a small hearth preserved in the first layer (C5) above Middle Palaeolithic deposits, which indicates an age similar to that of a modern human maxillary previously analysed and re-dated here from 36,014 to 34402 cal BP, confirming its stratigraphic attribution. The Middle Palaeolithic lithics at the site were first described as para-Charentian cultural facies following typological analyses. The revision of the earlier collection supplemented with the new material, using a technological approach, allow to identify two layers dominated by Levallois production followed by discoid production (Layers C8 and C6) surrounding an original assemblage (layer C7), characterised by a dominant Levallois production completed by three secondary production systems of equal importance, including discoid, SSDA and a Quina-like production. The faunal spectrum predominantly comprises an assemblage of Pleistocene large mammals, and biochronological studies corroborate the dates obtained. [ABSTRACT FROM AUTHOR]

The Upper Palaeolithic (UP) record of the Zagros Mountains is of critical importance for our understanding of the dispersal of modern humans into Southwest Asia. Most researchers interpret the record as reflecting the existence of two developmentally related cultural groups, the Baradostian of the early UP and the Zarzian of the late UP or Epipalaeolithic. In this paper we analyse techno-typological characteristics of early UP assemblages from the Zagros to assess the degree of variability. We use here new chronometric and typo-technological data from the early UP assemblages of the cave site Ghār-e Boof in the north western Fars province of Iran and compare these data with key sites of the Zagros UP, including Shanidar, Warwasi and Yafteh. Our study reveals important technological differences between assemblages from these sites, which led us to argue that the UP record of the Zagros Mountain range reflects multiple technological traditions instead of a single one. We further argue that a model reflecting a mosaic pattern for the evolution of the early UP in the Zagros Mountains fits better with the increasing evidence for a chronologically deep and spatially complex process of the spread of modern human populations over Southwest Asia.

At the Middle-Upper Palaeolithic (M/UP) transition in Western Europe, hominins depended mostly on terrestrial mammals for subsistence, being pointed out that reliance on reindeer ( Rangifer tarandus ) would have promoted declines in human population densities during that period. Food-composition tables have been compiled for hominins at the M/UP transition, listing protein, fat, energy, different omega-3 fatty acids and ascorbic acid concentrations. These data were used to compute the regular relations between fatty and lean tissues of the main hunted food-animals to meet hominin energy needs. Then, with daily protein intake considered critical, the optimal contribution of the different omega-3 fatty acids from different hunted species to hominin diets were computed. Several faunal assemblages from different human sites at different M/UP periods were used to assess the overall daily intake of the various omega-3 fatty acid classes. The results of the calculations made in this work are quite clear; hominins at the M/UP transition had a deficit of both omega-3 fatty acids and ascorbic acid. Data on human organs summarized here are also conclusive: these contain such nutrients in amounts much higher than reached in the corresponding mammal organs consumed, and thus could have been alternative sources of those nutrients for Palaeolithic hominins. Therefore, nutritional cannibalism detected at such times could have had the function of alleviating these deficits. The evolutionary advantages gained by the consumption of the various omega-3 fatty acids of human origin are also discussed. [ABSTRACT FROM AUTHOR]

There is increasing evidence that humans have exploited intertidal and shallow-water species for much longer than has been previously considered, and certainly not restricted to Anatomically Modern Humans (AMH). One of the principal reasons for the lack of evidence up till recently has been a lack of consideration for the temporal and spatial backdrop to such activities throughout human evolution, in particular related to changes in sea-level during the Pleistocene (Bailey et al., 2008). This study reports on the marine molluscs excavated from Gorham's Cave between 1998 and 2005, focussing in particular between levels III and IV, corresponding to the Upper (AMH) and Middle Palaeolithic (Neanderthals), respectively. Given that Gorham's Cave was never more than approximately 2 km away from the coastline, it still preserves evidence of exploitation of marine molluscs for food by Neanderthals and in this article the data obtained are compared across the Middle–Upper Palaeolithic transition. The results obtained suggest a high degree of consistency in the mode of marine mollusc exploitation between levels, and comparisons with extant communities supports the contention that marine molluscs were exploited in direct proportion to their relative abundance and accessibility. Patterns in shell size distributions for some of the main species exploited are discussed, as are possible anthropic valve selection and the marine climatic signals that can be extracted from such data. The main difference that emerges between Upper and Middle Palaeolithic levels was a lack of evidence of collection for decoration in Middle Palaeolithic levels, but even here the relatively small size of the Level IV sample precluded totally excluding this possibility based only on absence of evidence.

Seeing Lithics represents a doctoral thesis submitted to Harvard University by Gilbert Tostevin in 2000. Tostevin is currently a professor of Anthropology at the University of Minnesota and has written extensively on human evolution, lithic technology, Old World archaeology, and Palaeolithic archaeology. These interests can be clearly seen in this book which develops a new theoretical and analytical approach to the study of cultural transmission in the Middle-Upper Palaeolithic transition.

Transformation in technological patterns associated with the Middle-to-Upper Palaeolithic transition between 50 and 40 ka in Western Europe and their relationship with the Neanderthal and Anatomically Modern Human populations and behaviors are issues that continue to stimulate heated debate. In this article we use the Middle and Early Upper Palaeolithic archaeo-stratigraphic record from the Bordes-Fitte rockshelter (les Roches d'Abilly site, Central France), a Bayesian analysis of the ages obtained by accelerator mass spectrometry radiocarbon on ultrafiltered collagen and by luminescence on quartz and feldspar grains, to establish a timeline for material culture and sedimentary dynamic changes during the Middle-to-Upper Palaeolithic transition. Technology, refitting studies and taphonomy of lithic artifacts recovered in the geoarchaeological field units D1 and D2 permit to characterize 3 reduction strategies (Levallois, Discoidal and Châtelperronian blade) that took place between the cold Heinrich events 5 and 4. We discuss the implications of the results to characterize the end of the Middle Palaeolithic, and for distinguishing anthropogenic and non-anthropogenic factors in Middle-to-Upper Palaeolithic assemblage's variability.

Abstract: The debate about the complex issues of human development during the Middle to Upper Palaeolithic transition period (45–35 ka BP) has been hampered by concerns about the reliability of the radiocarbon dating method. Large 14C anomalies were postulated and radiocarbon dating was considered flawed. We show here that these issues are no longer relevant, because the large anomalies are artefacts beyond plausible physical limits for their magnitude. Previous inconsistencies between 14C radiocarbon datasets have been resolved, and a new radiocarbon calibration curve, IntCal09 (), was created. Improved procedures for bone collagen extraction and charcoal pre-treatment generally result in older ages, consistent with independently dated time markers. [Copyright &y& Elsevier]

Abstract: The Middle to Upper Palaeolithic transition is the key period for our understanding of Neanderthal and modern human interactions in Europe. The site of Les Cottés in south-west France is one of the rare sites with a complete and well defined sequence covering this transition period. We undertook an extensive radiocarbon dating program on mammal bone which allows us to propose a chronological framework of five distinct phases dating from the Mousterian to the Early Aurignacian at this site. We found that the Mousterian and Châtelperronian industries are separated from the overlying Protoaurignacian by a gap of approximately 1000 calendar years. Based on a comparison with Upper Paleolithic sites in Europe we see an overlap in the ages of Châtelperronian industries and Aurignacian lithic assemblages, which are usually associated with Anatomical Modern Humans, which is consistent with an acculturation at distance model for these late Neanderthals. The Proto and Early Aurignacian appear contemporaneous indicating that this transition was rapid in this region. Anatomically Modern Humans are present at the site of Les Cottés at least at 39,500 cal BP roughly coincident with the onset of the cold phase Heinrich 4. [Copyright &y& Elsevier]

Abstract: Geoarchaeological analysis of the Middle and Upper Palaeolithic record preserved in cave, rock-shelter and open-air sites in the northern sector of the Meso-Cenozoic of the Western Iberian Peninsula margin (Portugal) reveals several disconformities (erosive unconformities), hiatuses and surface stabilization phases. A recurrent disconformity, dated to ca. 29,500–32,000calyr BP, in the time range of Heinrich event 3, must correspond to a main erosive event related to the impacts of climate change on the landscape, including a reduction in vegetation cover and altered precipitation patterns, with the consequent accelerated down-cutting by stream systems, slope reactivation and endokarstic reorganisation, causing the erosion of sediments and soils accumulated in cave, rock-shelter and open-air sites. These processes create a preservation bias that may explain why Early Upper Palaeolithic finds in primary deposition context remains exceptional in the carbonate areas of central-western Portugal, and possibly elsewhere in the other places of Iberia. The impact of such site formation processes must therefore be duly considered in interpretations of the current patchy and scarce archaeological record of the Middle-Upper Palaeolithic transition in south-western Iberia.

Abstract: This paper presents new AMS radiocarbon dating results of six ungulate bones from the current excavation of Isturitz Cave, France, layer C 4c4. The assemblage from this layer exhibits a suite of traits closely aligned with the Early Aurignacian, but with some aspects that bear strong similarities with the Protoaurignacian, with possible in situ technological transformation. Accurate and precise dating of the late Middle Palaeolithic and the early Upper Palaeolithic periods is critical to our understanding of the possible relationship between final Neanderthals and early modern humans in Europe. As such, a rigorous set of sample selection and evaluation protocols was developed and used in this research. Among these, only cutmarked bones were selected and a total of 31 targets were made, giving a weighted average of 37,180±420BP for this assemblage and providing a terminus ante quem for the ornaments, decorated artefact and amber pendants beneath it. The implications and importance of these results to debates concerning the chronological relationship between the Châtelperronian, Protoaurignacian and Early Aurignacian and associated debates regarding hominin dispersal, interaction and the timing of technical and cultural innovations are discussed.
