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 ...

The territory of Moravia is well known for its high density of Early Upper Paleolithic sites. However, the majority of sites are surface sites lacking chrono-stratigraphic data. To further our understanding of the technological development, and replacement of Neanderthals by Anatomically Modern Humans between 50-40 kya, necessitates the discovery of new stratified sites. We implemented a project aimed at discovering new EUP sites with intact sediments. Central part the Bobrava Highland is an important EUP microregion and is located on the southwestern margin of the Brno Basin. We relocated almost all previously published sites in the area and conducted surface surveys in an attempt to discover additional surface sites. At each site we recorded the artifact clusters in absolute coordinates, and searched for potential artifacts in the intact sediments, often along the edges of surface artifact clusters. We have located intact sediments at four sites previously recorded as surface sites. We found in situ artifacts at two of the sites. The developed and successfully tested survey strategy may have potential application for surveys in other microregions., Petr Škrdla ... [et al.]., and Obsahuje seznam literatury
