The surface surveys over the Mohelno highland plateau microregion, bordered by Oslava River to the north and Jihlava River to the south, have a long tradition with many resultant collections. Part of those collections that were available for study to the authors (including their own fi nds) were reanalyzed. Generally, this microregion is distinctive due to its specifi c Early Upper Paleolithic industry (or industry from the Middle to Upper Paleolithic transitional period) combining Levallois technique and bifacial reduction. Although the association of these two components is an important question for current archeology, the material from this microregion cannot be used for addressing this question because the collections are from surface scatters so the level of assemblage homogeneity and chronological control cannot be established. Although the local Krumlovský les-type chert dominates the raw material spectra, imports of Stránská skála-type chert and radiolarite also occur. Other raw materials include local siliceous weathering products, Cretaceous spongolite chert and rock crystal. In addition, Aurignacian occupation (with prevailing erratic fl int in raw material spectra) was documented at one site, supplemented by several isolated finds., Petr Škrdla ...
