Variabilité de l'industrie lithique entre les structures de l'habitation no 1 de Mezhyrich, site du Paléolithique supérieur d'Ukraine

The investigation of the lithic assemblages from three archaeological structures of the Upper Palaeolithic Mezhyrich site, mammoth bone dwelling no. 1, nearby located pit no. 7 and workshop with a portion of cultural layer situated on the border of the pit, exhibits a sufficient diversity of the main indexes of flint assemblages. According to the latter, the main flint resources, cores and large pieces of flint, as well as blades and several tools (scrapers), were kept just in the dwelling. At the same time, the remains of “debitage” and the modification products of several tools (burin spalls) are more numerous in the pit and the workshop. The higher percentages of backed microliths, included the forms with diagnostic projectile impact fracture, and burins with several working edges are also observed in the assemblages of the last two archaeological structures.
