Kenyapotamus is an extinct ancestor of the modern Hippopotamus which lived in Africa roughly 16 million to 8 million years ago during the Miocene epoch. Its name is derived because its fossils were found in modern-day Kenya.
Although little is known about the Kenyapotamus, it's dental pattern bore similarities to that of the genus Xenohyus, a European Tayassuid from the Early Miocene. This led some scientists to conclude that Hippopotami were most closely related to modern peccaries and pigs[1].
More recent research has suggested that Kenyapotamus and the entire Hippopotamidae family may be more closely related to Cetaceans[2].
