Lithic economy in South Western France during the Neolithic: A case study from a coastal site - La Lède du Gurp (Aquitaine)
Résumé
The prehistory of South-western France is known worldwide for its rich record of Palaeolithic sites, especially from the Dordogne region. However, while research on the Palaeolithic is extremely prolific, the Neolithic was at the same time relegated to the background. Since the beginning of the discipline, few researchers worked on the Neolithic from SW France. Besides, they focused on ceramic typological analyses to describe cultural groups, rarely considered lithic tools and armatures, and never performed any techno-economical study of lithic productions. For over thirty years, rescue archaeology excavations revealed a large presence of Neolithic sites for this period; nonetheless Neolithic research remains little developed in relation to its potential. As part of my PhD thesis, the aim will be to fill this gap by characterizing lithic productions through techno-economical analyses, in order to describe the cultural groups existing in Northern Aquitania during the 4th and the 3rd millennia. With the example of La Lède du Gurp, a littoral occupation site dated to the middle and recent Neolithic, I will try to highlight in this paper what the study of lithic industries can say about a cultural group at a local scale. The reconstitution of the operating chains and the statistical analysis of small assemblages of non-standardised lithic reduction, allowed us to highlight a similar low investment in lithic production between the Middle and the Recent Neolithic of La Lède du Gurp. Our approach has enabled us to observe that a low investment in lithic production may reflect the complexity of the Neolithic groups and the complementarity of lithic industry with other technical subsystems directly related with the group's natural environment, as may it be the case for salt production during Recent Neolithic at La Lède du Gurp.
