Étude techno-économique du Moustérien de Pradayrol (Caniac-du-Causse,Lot) : entre mobilité des ressources lithiques et adaptation aux matériaux locaux,un exemple de gestion complémentaire des quartz et silex au Paléolithique moyen récent en Quercy

The Mousterian locus at Pradayrol (Caniac-du-Causse, Lot, France) produced an important lithic assemblage, composed primarily of quartz, alongside a varied flint component. Our technological analysis reveals the presence of several chaînes opératoires adapted to the morphology and mechanical properties of different raw materials. This is especially evident in the use of the bipolar on-anvil technique on quartz cobbles and discoidal flaking methods on both quartz and relatively local flints. Flint from the Périgord region provides evidence for a fragmented and ramified Levallois chaîne opératoire, different from that observed with local raw materials. These techno-economic features are similar to those documented for many late Middle Palaeolithic assemblages in the Quercy. The Neanderthal occupation of Pradayrol seems to reflect a balance between technical know-how and adaptations to the raw material constraints.
