Paleolithic bifacial artefacts from Eastern Bohemia

Four Paleolithic lithic artefacts that were produced using the bifacial technique are currently known from the territory of Eastern Bohemia. Three of them, namely a knife from Bolehošt’ and leafpoints from Jaroslav and Černčice, were subjected to traceology analysis and 3D models of these artefacts were created. These models served as a basis for enhanced visualisation of their surface features using APSS surface analysis. Although in the case of the knife from Bolehošt’ and the point from Jaroslav no traces could be detected by tracer analysis, the point from Černčice can probably be interpreted as a knife on the basis of this method. One of the fractures on the artefact is also interesting, which seems to be the result of its re-shaping during the Paleolithic. The APSS analysis, in turn, has been proved to be a very promising tool for the documentation of lithic artefacts whose surface is also heavily weathered.
