Kenyapotamus is a possible ancestor of living hippopotamuses that lived roughly 16 million to 8 million years ago during the Miocene epoch. 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]
