抄録

New dental and astragalar specimens of a primitive hippopotamus, Kenyapotamus coryndonae (Mammalia, Cetartiodactyla, Hippopotamidae, Kenyapotaminae) from the lower Upper Miocene Nakali Formation at the Nakali locality, central Kenya, are described and illustrated. The new specimens increase the known morphological and size variations of the dentition and astragalus in this primitive hippopotamid species, which is important to understand the origin and early evolution of the Hippopotamidae.
