Elemental records in teeth reveal prehistoric seasons of Neanderthal birth, weaning, childhood illness, and neurotoxic exposures.

Neanderthals are often considered as less technologically advanced than modern humans. However, we typically only find faunal remains or stone tools at Paleolithic sites. Perishable materials, comprising the vast majority of material culture items, are typically missing. Individual twisted fibres on stone tools from the Abri du Maras led to the hypothesis of Neanderthal string production in the past, but conclusive evidence was lacking. Here we show direct evidence of fibre technology in the form of a 3-ply cord fragment made from inner bark fibres on a stone tool recovered in situ from the same site. Twisted fibres provide the basis for clothing, rope, bags, nets, mats, boats, etc. which, once discovered, would have become an indispensable part of daily life. Understanding and use of twisted fibres implies the use of complex multi-component technology as well as a mathematical understanding of pairs, sets, and numbers. Added to recent evidence of birch bark tar, art, and shell beads, the idea that Neanderthals were cognitively inferior to modern humans is becoming increasingly untenable.

New fieldworks and revision of lithic collections during the past decade have renewed our interpretation of the timing and characteristics of the earliest Acheulean techno-complexes in Western Europe. The lower level of the la Noira site is a crucial snapshot for evaluating the technological abilities and strategies of Middle Pleistocene hominins at 700 kyrs in Europe at the beginning of elaborate biface production and associated behavioural changes. The site of la Noira is located in the central part of France, where climatic conditions may have had a stronger impact on occupations than in Southern Europe. New excavations between 2011 and 2018, over a surface of 100 m², yielded a large corpus of artefacts including cores, flakes, bifaces and a large heavy-duty component. We analysed the lithic corpus composed of almost 1,000 artefacts from a taphonomic perspective, identified the chaînes opératoires and all the reduction processes involved at the site, and examined the spatial distribution of the archaeological remains. The results offer a broad overview of the types of lithic management and related cognition and skills of Middle Pleistocene hominins living on a riverbank under cool conditions, at the beginning of a glacial stage.The comparison with penecontemporaneous sites indicates that a technological shift possibly occurred in Western Europe from 700 to 600 kyrs. The technological strategies used indicate (1) common abilities in core technologies including some sporadic independence from stone shape, (2) a diversity of technical solutions and morphological results for biface shaping with evidence of a bifacial or bilateral equilibrium and a preconceived form on some tools, and (3) a large and diversified heavy-duty component. Biases related to activities, raw material types and various traditions are discussed. The chronology of the emergence of new behaviours, such as an early biface shaping ability, seems to have been identical in the northwest and south of Europe.

Level 4.1 from the Abri du Maras (Ardèche, France) is chronologically attributed to the beginning of MIS 3 and is one example of late Neanderthal occupations in the southeast of France. Previous work on the faunal and lithic remains suggest that this level records short-term hunting episodes of reindeer associated with fragmented lithic reduction sequences. During fieldwork, the high density of the material did not allow identification of clear spatial patterning of these activities. In order to try to decipher the palimpsest of these short-term occupations, we combined contextual micro-stratigraphic analysis with interdisciplinary and methodological approaches to obtain high-resolution intra-site spatial data. The former was performed by studying microfacies variability of occupation layers at meso to microscales. A combination of spatial techniques based on GIS and kernel density analysis, along with faunal and lithic refitting was used and focused on the horizontal distribution of the whole archaeological assemblage.The results demonstrate that quantitative approaches, associated with the interdisciplinary empirical processing of data, are suitable and adequate methods for describing the spatio-temporal formation of the archaeological assemblage. This integrated approach allowed us to identify a temporal succession of occupational events marked by distinctive anthropic imprints in the host matrix in well-preserved activity areas. The analysis of their spatial patterns reveals differential treatment of lithic and faunal remains. We describe the possible organization of the settlement patterns dynamics of these specialized short-term occupations.

The study of the lithic assemblages of two French sites, the Bau de l’Aubesier and Payre, contributes new knowledge of the earliest Neanderthal techno-cultural variability. In this paper we present the results of a detailed technological analysis of Early Middle Palaeolithic lithic assemblages of MIS 8 and 7 age from the two sites, which are located on opposite sides of the Rhône Valley in the south-east of France. The MIS 9–7 period is considered in Europe to be a time of new behaviours, especially concerning lithic strategies. The shift from the Lower Palaeolithic to the Early Middle Palaeolithic is “classically” defined by an increase in the number of core technologies, including standardized ones, which are stabilized in the full Middle Palaeolithic (MIS 5–3), associated with the decline of the “Acheulean” biface. Applying a common technological approach to the analysis of the two assemblages highlights their technological variability with respect to reduction systems and end products. Differences between Payre and the Bau de l’Aubesier concerning raw material procurement and faunal exploitation only partially explain this multifaceted technological variability, which in our opinion also reflects the existence of distinct technological strategies within the same restricted geographic area, which are related to distinct traditions, site uses, and/or as yet unknown parameters.

For the past decade, debates on the earliest evidence of bifacial shaping in Western Europe have focused on several key issues, such as its origin (i.e., local or introduced), or on what should define the Acheulean culture. Whatever hypotheses are proposed for its origin, the onset and technological strategies for making Large Cutting Tools (LCTs), including biface production, are key issues and are often associated with other behavioural changes, such as increased core technology complexity. Current archaeological patterns do not support the existence of transitional industries. Rather, the scant evidence suggests that biface production associated with the management of bifacial volume was widespread around 700 ka. Among the earliest sites, the site of Notarchirico in Southern Italy stands out as one of the most significant examples. 40Ar/39Ar ages and ESR dates recently provided a revised chronology for the whole sedimentary sequence and constrained the archaeological levels between ca. 610 and 670 ka. Five archaeosurfaces (A, A1, B, D and F) yielded LCTs, including bifaces, during Marcello Piperno’s excavations from 1980 to 1995. In light of this new chronological framework, which is much shorter than previously thought, we propose in this contribution a revision of the bifaces by applying the “chaine opératoire” method for the first time (analysis of reduction processes). Our goals are to assess biface production in this early Western European locality and to characterize the strategies applied at the site throughout the sequence. A corpus of 32 tools was selected from the A-A1, B, D and F archaeosurfaces. The technological analysis shows that hominins had the capacity to manage bifacial volumes, when raw material quality was adequate. Clear differences do not emerge between the different levels in terms of shaping modes or final forms. However, we demonstrate that the oldest level (level F), with the richest corpus, lacks flint and displays a higher diversity of bifaces. This ability to manage bifacial and bilateral equilibrium, as well as the diversity of the morphological results, is observed in a few penecontemporaneous sites (700–600 ka), both in the north-western and southern parts of Western Europe. These patterns suggest that hominins mastered well-controlled and diversified biface production, combining intense shaping and minimal shaping, and shared a common technological background regardless of the geographical area, and applied this technology regardless of the available raw materials. The degree of skill complexity of hominins in Western Europe between 700 and 600 ka, the current lack of evidence suggesting “gradual industries” between core-and-flake series and Acheulean techno-complexes, raise numerous questions on the origin of new behaviours in Western Europe, their mode of diffusion, and their association with Homo heidelbergensis or other Middle Pleistocene populations.
