Hexaprotodon

Hexaprotodon is an extinct genus of hippopotamid known from Asia and possibly Africa and Europe. The genus name Hexaprotodon comes from Ancient Greek ἑξα- (hexa-), meaning "six", πρῶτος (prôtos), meaning "first", and ὀδούς (odoús), meaning "tooth", therefore, "six front-teeth" as some of the fossil forms have three pairs of incisors. The pygmy hippopotamus was historically placed in the genus, but today is generally placed in its own genus. The core Asian members of the genus ranged from the Indian subcontinent to Southeast Asia, and are thought to have had an aquatic ecology similar to that of the living common hippopotamus. The last members of the genus became extinct during the Late Pleistocene, perhaps as recently as 15,000 years ago.
