Two little-known trilobites from the Bohemian Upper Ordovician

Journal of the Czech Geological Society, volume 46 (2001), issue 3-4, 219 - 226

Description of Decoroproetus ? aff. solus from the Zahořany Formation (Upper Ordovician, Berounian Stage) is presented. Although this species is poorly known and is left in open nomenclature, it is and important element in the Bohemian trilobite faunas implying a probable communication of the Prague Basin with other sedimentary basins in the Peri-Gondwanan area during the Berounian Stage. Based on new findings, the description of Eudolatites simaki from the Králův Dvůr Formation (Upper Ordovician, Kralodvorian Stage) is supplemented. especially with regard to the preservation and intraspecific variability. This species is assigned to Dreyfussina with some reserve.
