This article proposes a biostratigraphic scheme for the Upper Cretaceous of the East European Platform on the basis of the distribution in the sections of three groups of microfossils: foraminifera (both planktonic and benthic), radiolarians, and nannoplankton. Most of the stage and substage boundaries are confirmed by macropaleontological data. The most divided units are those distinguished based on benthic foraminifers and nannoplankton. The diversity of these microfossils and their constant presence allowed us to identify zones and subzones, while it is possible to subdivide only the beds by planktonic foraminifers and radiolarians. The most favorable stages in the development of plankton biota can be considered the Turonian–Coniacian interval when the basins of the East European Platform experienced an intensive influence from warm waters of the Tethys Ocean. The global Campanian cooling is clearly recorded, which affected the taxonomic diversity of all microfossil groups.
