The significant development of predetermined flake technologies marks the beginning of the Middle Paleolithic in Europe. This phenomenon is not only expressed by the increase in the Levallois methods, but it also includes a diversity of other flaking methods, e.g. micro-Levallois, Kombewa, truncated-faceted and Le Pucheuil, often related to secondary reduction sequences. The tool management and use patterns they fulfill are still largely unknown due to the scarcity of use-wear analyses, whereas their technological characteristics are well defined.

In this paper we present a combined technological and functional study of Le Pucheuil-type flakes (Delagnes, 1993), from the eponymous Early Middle Paleolithic site of Le Pucheuil (northwestern France). The technical investment during the reduction sequence is relatively low but flaking is nevertheless guided by specific and constant technical rules which result in the production of predetermined flakes. These flakes share common morphotechnical attributes: an acute, straight or slightly curved, distal edge opposed to a robust and wide proximal area. The use-wear analysis shows that this morphology was clearly sought after insofar as the distal acute edges were used as working edges while the proximal edges served as prehensile areas. Despite their similarity, Le Pucheuil-type flakes were used for a variety of tasks, including butchery but also hide scraping, wood and non-woody plant working. Tool management suggests that their production responded to deferred and/or collective uses. Our combined approach points to: 1. the high degree of elaborateness and flexibility of the tool management strategies developed in the Early Middle Paleolithic in Europe, 2. the presence of long-lasting and multi-activity occupations in an open-air context during the harsh environmental conditions at the beginning of the penultimate glaciation (OIS 6). The results finally show the great potential of combined technological/functional approaches to lithic assemblages as a way to refine our understanding of the technical, social and economical organization of Neanderthal hunter-gatherers, most specifically in contexts where lithics are the only preserved materials (source : éditeur).
