【 摘 要 】

Eleven species belonging to ten genera, i.e. Discradisca Stenzel, 1964, Novocrania Lee&Brunton, 2001, Terebratulina d’Orbigny, 1847, Megathiris d’Orbigny, 1847, Argyrotheca Dall, 1900, Bronnothyris Popiel-Barczyk & Smirnova, 1978, Joania Álvarez, Brunton & Long, 2008, Megerlia King, 1850, Platidia Costa, 1852, and Lacazella Munier-Chalmas, 1880 have been identified in the Upper Eocene (Priabonian) deposits of Dnipropetrovsk, eastern Ukraine. Two species, Bronnothyris danaperensis sp. nov. and Joania ukrainica sp. nov. are described as new. The genera Discradisca, Novocrania, Megathiris, Joania, Megerlia and Platidia are reported for the first time from the Eocene of Ukraine. Additionally, the occurrence of Joania and Megerlia extends their stratigraphical range from the Oligocene to the Eocene. The fact that megathyridids and thecideides make up more than 90% of the material indicates that the fauna was living in a warm, shallow-water environment.
