New baleen whale genera (Cetacea, Mammalia) from the miocene of the northern caucasus and ciscaucasia: 1. Kurdalagonus gen. nov. from the middle-late Sarmatian of Adygea

A revision of previously known material and analysis of new records of Miocene baleen whales from the Sarmatian of Adygea (city of Maikop, Blinovo Formation) resulted in the establishment of a new genus, Kurdalagonus with three species: K. mchedlidzei sp. nov. (Middle Sarmatian, Nagiezh-Uashkh locality), K. adygeicus sp. nov. (Upper Sarmatian, Hydroelectric power station locality), and K. maicopicus (Spasskii, 1951) (=Cetotherium maicopicum Spasskii, 1951; Middle Sarmatian, Hydroelectric power station locality).
