Analyse du débitage laminaire du site de Mezhyrich : habitations no 1, 2 et 3

This article presents the results of technological analyses of the laminar products from three bone dwelling structures from the Mezhyrich site (dated to Upper Palaeolithic; 15,000-14,500 years BP). More than 2500 blades and bladelets were studied from technological point of view. We find close similarity between the three dwellings, which reflects similar ways of preparation of core fracture zone (overhang reduction, butt abrading, and flaking surface isolation), as well as in the organization of the negative of the dorsal surfaces of the blades. The comparison with materials from the Kostenki 1 layer 1 site (upper layer, 22,000-24,000 years BP) shows some differences with the artefacts from Mezhyrich site, despite same technological methods. This could be explained by differences in cultural tradition and large time gap between these two sites. The complexes from Mezhyrich to follow the Kostenki 1/1 tradition but with their own particularities.
