The first report of the bivalved arthropod Tuzoia from the Skryje-Tyrvovice Basin (Barrandian area, Czech Republic)
Abstrakt
fragment of a Burgess Shale-type fossil, bivalved arthropod Tuzoia Walcott, 1912, is described from shales of the mid-Cambrian Buchava Formation in the Skryje-Tyrovice Basin, Central Bohemia, Czech Republic. It is the second recorded find of Tuzoia from West Gondwana.
Uncrushed and uncoloured preservation of the tuzoiid valve is consistent with the very thin non-mineralised cuticle described for this taxon. This new occurrence of the genus Tuzoia, as well as the earlier described genera Wiwaxia and Hurdia, indicate the presence of a Burgess Shale-type fauna in several stratigraphical levels of Cambrian sequence of the Skryje-Tyrovice Basin.
Distribution of other exceptionally preserved specimens established in the Buchava Formation is briefly summarized and discussed.
