The mixing of boreal and Mediterranean/Tethyan calcareous nannofossils was observed in the Campanian sediments of the Zdanice Unit in Southern Moravia. The first occurrence of these high- and low-latitude species, and their correlation with standard and boreal nannoplankton zonations have been compared. The presence of Petrarhabdus copulatus probably indicates an influence on this depositional area by the Indian and South Atlantic oceans.
