title: NANNOPLANKTON STRATIGRAPHY OF UPPER CRETACEOUS OF MAUNTINE CRIMEA
abstract: On the south of Ukraine Upper Cretaceous calcareous nannoplankton reached its maximum of quantity and quality. Nanofossils are rockbforming components of all lithological rock types, however, the weak variation of the taxonomic diversity complicate the application of the stratigraphic groups. Based on the study of material from the Upper Cretaceous range of Mountain and Plain Crimea region we have identified nine zones of global distribution. In the lower Cenomanian of the zone of Eiffelithus tu
