The Middle to Upper Paleolithic (MP/Up) transitional period and the question of a replacement of Neanderthals by Anatomically Modern Humans is a crucial question in current Archaeology and ANthropology. However, without the discovery and excavation of new Early Upper Paleolithic (EUP) sites, no progress in the issue of the MP/UP transitional period in the Middle Danube Region would be possible. The systematic and repeated surface surveys on the site of Tvarožná-Za školou (Fig. 2) resulted in an important Bohunician artifact assemblage. Among the important features of thsi assemblage is an equal ratio of Stránska skála type adn Krumlovský les type cherts, which are supplemented by non-specified Moravian Jurassic cherts, Cretaceous spongolite cherts, radiolarite, and erratic flint. The industry is characterized by the absence of bifacial reduciton and the application of Levalloisian technology on all recognized types of raw material. Because the test pits excavated during 2006-2008 yielded arfifact within intact sediments, a larger and more complex excavation was realized during summer 2008 and a continuation is planned for 2010. The straifiied collection from Tvarožhná will contribute to the knowledge about the EUP in MOravia by clarifying the chronology and homogeneity/heterogenity of Bohunician collections (cf. hypothesis in Tostevin, Škrdla 2006). Another important issue is the cmoparison of the surface and excavated collection from the same site. While the surface collection was already published (Škrdla 2007), this arcitcle presents field results and preliminary interpretations from the 2008 season., Petr Škrdla ...
