Periodic Reporting for period 1 - LION (L'industrie oubliée de Néandertal - The forgotten industry of Neanderthal)
Période du rapport: 2019-10-01 au 2021-09-30
For a long time, the “retouchers”, used in lithic knapping, were the only Neanderthal bone tools frequently reported. Collected among butchery remains, unshaped and discarded in situ after a short-term use, they gave a picture of a poorly mastered and opportunistic use of bone. Other types of tool were identified from time to time, but the rarity of specimens, their minimal shaping, often done by percussion as for lithic tools, and the difficulty of determining their function, reinforced the idea that Neanderthal did not understand the specificities of the bone material.
The recent discovery of more than one thousand bone tools at the Neanderthal site of Chagyrskaya cave in Siberia, by means of a technological and use-wear analysis applied to faunal remains, allowed to question this assertion. The number of tools, their diversity and recurrence are characteristic of an industry and show that these Siberian Neanderthals made a daily use of bone to meet specific needs. Nevertheless, we did not know if this isolated discovery was a regional particularity or if it could be a more general phenomenon, disregarded due to the lack of an adequate conceptual and methodological frameworks. To test these hypotheses, we searched, with the same analytical grid as applied at Chagyrskaya cave, for bone tools in Neanderthal sites located in Western Europe, where the first Neanderthal bone tools were mentioned more than a century ago.
Thanks to this work, the objectives have been achieved. It demonstrates than a Mousterian bone industry does exist in Western European sites and provides further evidence confirming that it was a common component of the Neanderthals productions. Microtomographic analysis made it possible to observe internal damages linked to manufacture and use of experimental tools and find similar features in the archaeological samples. They also shown that the damages differ according to the stress undergone by the tools. Internal damages can therefore be an additional clue, along with surface damages, for the characterisation and interpretation of bone tools manufacturing and function. These results open two new investigation fields. The Neanderthal bone industry, which was disregarded, has now to be systematically sought in Middle Palaeolithic sites across Eurasia. It will shed new light on the Neanderthals behaviour and will contribute to a better identification of their specificities. The development of an effective methodology for the recognition of internal markers from use and manufacture can be useful, not only for Neanderthal’s studies, but for all technological and functional analysis applied to any bone artefacts regardless of their age and maker. Data provided by our research, which can be easily shared because of the full 3D modelling of the tools, now need to be completed and specified through a broader application of the method.
We hope that the results of the LION project, which are already being disseminated through scientific articles and upcoming lectures, will encourage other researchers and students to invest in this topic, both archaeologically, by taking into account this new component of Neanderthal productions, and methodologically, by enriching the frame of reference for the technological and functional interpretation of the pre-Sapiens bone industries. We also hope, through online dissemination and public event, to reach a wider audience and contribute to change the way we use to look at the ancient humanities.
