Its name reflects that its fossils were first found in modern-day Kenya. Although little is known about Kenyapotamus, its dental pattern bore similarities to that of the genus Xenohyus, a European suid from the Early Miocene. This led some scientists to conclude that hippopotami were most closely related to modern peccaries and suids.[2] Recent molecular research has suggested that hippopotamuses are more closely related to cetaceans than to other artiodactyls. A morphological analysis of fossil artiodactyls and whales, which also included Kenyapotamus, strongly supported a relationship between hippos and the anatomically similar family Anthracotheriidae. Two archaic whales (Pakicetus and Artiocetus) formed the sister group of the hippopotamid-anthracotheriid clade, but this relationship was weakly supported.[3] References1. ^{{Cite journal| author = Pickford, Martin | year = 1983 | journal = Geobios | location = Lyon | volume = 16 | pages = 193–217 | title = On the origins of Hippopotamidae together with descriptions of two new species, a new genus and a new subfamily from the Miocene of Kenya | doi = 10.1016/S0016-6995(83)80019-9| issue = 2}} {{Taxonbar|from=Q2899857}}{{paleo-eventoedungulate-stub}}2. ^Petronio, C.
