Par opposition à ceux de l’Aurignacien, les ensembles lithiques gravettiens procèdent selon une méthode rappelant le Levallois quant à la préparation des supports. Mais les variations observables au sein du Gravettien touchent autant les processus de symbolisation dans l’art et les sépultures. Elles affectent différents substrats eurasiatiques, plutôt septentrionaux, comme mis en réserve dès les Néandertaliens. [less ▲]

The scope of this article is to propose an innovative method based on Near Infrared Hyperspectral Chemical Imaging (NIR-HCI) to rapidly and non-destructively evaluate the relative degree of collagen preservation in bones recovered from archaeological contexts. This preliminary study has allowed the evaluation of the potential of the method using bone samples from the Early Upper Palaeolithic, Mesolithic and Neolithic periods at the site of Trou Al'Wesse in Belgium. NIR-HCI, combined with chemometric tools, has identified specific spectral bands characteristic of collagen. A chemometric model has been built using Partial Least Squares Discriminant Analysis (PLS-DA) to identify bones with and without collagen. This enables the evaluation of the degree of collagen preservation and homogeneity in bones within and between different strata, which has direct implications for archaeological applications (e.g., taphonomic analyses, assemblage integrity) and sample selection for sub- sequent analyses requiring collagen. Two archaeological applications are presented: comparison between sub-layers in an Early Upper Palaeolithic unit, and evaluation of the range of variability in collagen preservation within a single Holocene stratum.

In Belgium, Palaeolithic research goes back to the early 19th century, in the wake of mining and quarry work. Geology and paleontology developed early and rapidly and were economically important. As a result, the earliest human history was reconstructed here entirely independently, by defining the Mousterian (Engis, 1830), Aurignacian (Montaigle), Gravettian (Trou Magrite) and Magdalenian (Chaleux) periods. Belgium, due to its central position, is in addition particularly representative of the wave of "modernity" that suddenly was adopted across northwest Europe, overlying a highly diverse and innovative cultural base during the time of the Neandertals. At this point in time, as in others, Belgium played the role of intermediary and incubator between the British Isles and the Rhineland, extending as far as the Loire. [less ▲]

The Late Pleistocene global extinction of many terrestrial mammal species has been a subject of intensive scientific study for over a century, yet the relative contributions of environmental changes and the global expansion of humans remain unresolved. A defining component of these extinctions is a bias toward large species, with the majority of small-mammal taxa apparently surviving into the present. Here, we investigate the population-level history of a key tundra-specialist small mammal, the collared lemming (Dicrostonyx torquatus), to explore whether events during the Late Pleistocene had a discernible effect beyond the large mammal fauna. Using ancient DNA techniques to sample across three sites in North-West Europe, we observe a dramatic reduction in genetic diversity in this species over the last 50,000 y. We further identify a series of extinction-recolonization events, indicating a previously unrecognized instability in Late Pleistocene small-mammal populations, which we link with climatic fluctuations. Our results reveal climate-associated, repeated regional extinctions in a keystone prey species across the Late Pleistocene, a pattern likely to have had an impact on the wider steppe-tundra community, and one that is concordant with environmental change as a major force in structuring Late Pleistocene biodiversity.

The AMS dates obtained for the Holocene sequence are stratigraphically coherent, and indicate occupations at Trou Al’Wesse during the Early, Late and Final Mesolithic phases and the during the Middle Neolithic. This paper presents an interpretation of the chronostratigraphy in light of the recently obtained dates. [less ▲]

The site of Trou Al’Wesse has been interpreted as a site of possible contact between Mesolithic and Neolithic populations, given the discovery of Neolithic ceramics and Mesolithic tools in stratum 4. However, recent excavations have also revealed the presence of three Early Mesolithic facies overlain by a Neolithic layer, while a Late Mesolithic presence is suggested for a fourth facies at the base of the terrace slope. Lithic and faunal analyses, as well as spatial analysis of the stratigraphic position of material recovered, indicate a clear separation of Mesolithic and Neolithic occupations. We present a new interpretation of the sequence of Holocene human occupations at Trou Al'Wesse in light of these data, arguing that the site was regularly occupied during the Early Mesolithic, forming a palimpsest of these visits, followed by an occupational hiatus and then re-occupation during the Late Mesolithic. The Early Neolithic is a separate occupation clearly unrelated to the Early Mesolithic underlying it, but ongoing fieldwork may recover data concerning the Final Mesolithic and its relation to the Early Neolithic at the site.
