title: Calcareous Nanoplankton in the Paleogene Deposits of the Bakhchisaray District (Southwest Crimea)
abstract: The calcareous nannoplankton of the Upper Paleocene and Eocene deposits from the Bakhchisaray district of the Southwest Crimea has been studied. It has been compared with the coeval complexes studied earlier and the following zones have been identified: the Kacha Formation corresponds to zones NP6–NP8 (?), the Bakhchisaray Formation is NP12, and the Simferopol Formation is NP13–NP14. According to the species composition, calcareous nannoplankton inhabited the normal salty shelf sea in the tropic
