Abstract
In the second part of the monograph, bivalves of the family Crassatellidae from the Upper Eocene Mandrikovka Beds of Dnepr (former city of Dnepropetrovsk, Ukraine) and its environs are described. The family Crassatellidae is represented by 25 species, 21 of which were established by the author. These species belong to the genera Crassatella (Crassatella) (seven species), Crassatella (Furvusa subgen. nov.) (one species), Crassatella (Bathytormus) (five species), Crassatina (Crassatina) (four species), Crassovella gen. nov. (four species), and Chattonia (three species). All of these taxa are described and provided with figures of type species. Species are figured in 15 plates. These taxa are mostly established on the shell material from the Upper Eocene beds exposed by the Rybalsky quarry in the city of Dnepr. Valves belonging to the new genus Crassovella and new subgenus Crassatella (Furvusa) come from the same beds. Three out of 25 species are described from a core of the same age, which was obtained during drilling in the vicinity of Dnepr (near the towns of Sinel’nikovo and Kamensky and the village of Vasil’kovka).
