Contribution à l'évolution du Micoquien en Europe Centrale

The evolution of the Micoquian in Central Europe: new discoveries of the Micoquian in Upper Silesia (Poland) : The new discoveries in Upper Silesia demonstrate the occurrence of Micoquian settlements before the Eemian at Dzierzyslaw 1, at Pietraszyn 49 and probably at Cyprzanow 3. They testify that there was a continuity of the evolution of the Micoquian between the penultimate glaciation and the Early Vistulian. We present here particularly the data concerning the Pietraszyn 49 site whose industry is attributed to the Warta stage (O.I.S. 6.) The technological analysis demonstrates an assemblage with a predominantly core technique over debitage. The bifacial tools comprise bifaces (bifaces with a Faustkeilblatt type back, leafe shaped handaxes); knife-scrapers which are asymetric (Prondnik type, Bockstein type and bifacial) and bifacial scrapers. The tools on flakes comprise simple convex scrapers, convergent scrapers and retouched flakes.
