Approche fonctionnelle de l’outillage lithique à l'aube de l'Holocène dans le nord-ouest de la France

Abstract : After a significant simplification of the flint reduction methods during the Azilian period, which broke gradually with Magdalenian standards, the return to sophisticated laminar productions during younger Dryas marks a strong split in the lithic tradition. Beyond a state of uncertainty towards chronological boundaries, the research which have been conducted for thirty years gives a good understanding about changes in flint production methods and aims. Even though most research focuses on palethnographic reconstitutions, the functional purposes of the flint industry and the chaînes opératoires in which flint tools are implicated remain insufficiently studied. And yet, these questions are of prime importance to meet the expectation of the palethnographic reconstitutions that archaeologists covet. To overcome this deficiency, the functional analysis of two north-western France sites (le Buhot site at Calleville, Eure ; la Fosse site at Villiers-Charlemagne, Mayenne) attributed to the Pleistocene-Holocene transition were undertaken. The contribution of this doctoral research can be appreciated at different spatio-temporal scales. In the short-term, the results raise striking contrasts between sites, as much in regard to the activities performed as to the debitage products economy, and improve the current model of settlement patterns. In the long-term, the interplay of techno-functional results and other archaeological data gives food for thought about changes in the technical systems and prehistoric economies.
