Brandtocetus, a New Genus of Baleen Whales (Cetacea, Cetotheriidae) from the Late Miocene of Crimea, Ukraine
A new cetotheriid baleen whale, Brandtocetus chongulek, gen. et sp. nov., is described from the late Miocene of Crimea, Ukraine. The type series is represented by three partial skulls with periotic bones and tympanic bullae, one of the three belonging to a juvenile. Brandtocetus chongulek has transv...
