Tetraconodon was an extinct genus of even-toed ungulates that existed during the middle and late Miocene in Asia (India, Pakistan, Thailand, Myanmar).^[2]^[3]^[4]

Description

The last two pairs of premolars of Tetraconodon were extremely large, while the first two premolars were small, a unique characteristic of tetraconodontinae not found in other suids.^[1]

Tetraconodon magnum was largest species, while T. malensis is the smallest.^[5] Originally known from only the oversized premolars, T. magnum was once believed to have reached sizes comparable to that of a hippopotamus or rhinoceros.^[6] Once more material was recovered, such size estimates were invalidated, but it was nonetheless a large suid.
