- Abstract
The study of nannofossils and dinoflagelate cysts from the Paleocene-Eocene transition in the Nasypnoe section, Eastern Crimea identified the bed corresponding to the global event referred as the Paleocene-Eocene Thermal Maximum (PETM). The assemblages of both groups of microphytoplankton display significant changes including the appearance of Rhomboaster spp., Discoaster anartios and D. araneus nannofossils and Apectodinium augustum and Wilsonidium pechoricum dinocysts featured for this event and major variations in the ratio of taxa resulted in domination of eutrophic and warm-water species. The paleoecological interpretation of nannofossil and dinocyst distribution suggests a drastic sea-level fall preceded the PETM and occurrence of two transgressive episodes during it.
