Abstract: A correlation study was performed on the Upper Turonian foraminiferal assemblage from two localities in NW Bohemia Upohlavy and Brezno and the localities including Dresden-Strehlen in Saxony, Turold in South Moravia and type locality of Klement in Lower Austria. The Upper Turonian sediments (Teplice Formation) from the Upohlavy quarry and the Brezno-Pd 1 borehole contained foraminiferal assemblage represented by abundant, well-preserved tests of agglutinated and calcareous species. Three levels of change of benthic foraminiferal assemblage was recognized in these sediments. The first change - the disappearance of Cassidella tegulata (Reuss), Praebulimina crebra Stemprokova, Gaudryina compressa Akimec and Dorothia pupa (Reuss). At the second change Gaudryina carinata Franke, Gaudryina laevigata Franke, Gavelinella berthelini (Keller) and Pyramidina kelleri (Vasilenko) appeared. The third less significant level is characterized by the disappearance of P. kelleri and G. laevigata.
