Les phases anciennes du Paléolithique moyen dans le Sud-Est et le Sud-Ouest de la France : étude des systèmes techniques lithiques

Abstract : The first evidence of Middle Palaeolithic behaviour occurred in a mosaic pattern during the late Middle Pleistocene in Europe. They are traditionally associated with the emergence of standardised flaking concepts and the disappearance of bifacial shaping. Lithic assemblages are attributed to the final Acheuean or early Middle Palaeolithic depending on the proportion of bifaces and Levallois concept. Our study focuses on two geographical areas in Southern France, both rich in flint deposits. In Southeastern France, several layers from Orgnac 3 were studied (MIS9-8). Those lithic assemblages permit us to perceive the Lower to Middle Palaeolithic transition in a same context. At the contrary, single layers from several sites were selected in Southwestern France between MIS 10 and 6. This selection allows us to consider ancient and recent margins from the transitional period, considering open-air sites and cave occupations. Layers studied are the L2/3 from la Micoque (MIS 10), layer 2 from Petit-Bost (MIS 9/8), layer7 from the Pech de l’Azé II (MIS 7/6) and the layer VIIa from Combe Brune 2 (MIS 7/6). The use of a technological and techno-morpho-functional approach cleared the main characteristic of these sites. Several flaking (Levallois, S.S.D.A., Quina, Discoïd etc.) and shaping concepts (bifaces, pebble tools) have been identified. On the basis of these data, the modalities of emergence of the Levallois concept in Southern France are discussed. Besides this concept, the presence of algorithmic methods, the ramification of reduction processes and the combined matrices (bifacial, trifacial and notches) appear as main characters of these early Middle Palaeolithic series.
