This article will tell you everything there is to know about the first giant mammals, known as pantodonts, that appeared 10 million years after dinosaurs went extinct. The article covers their history, range, diet, behavior and much more.

The Coryphodon is an extinct genus of large mammals. It was a pantodont and was a member of the first group of large browsing mammals. Originally it lived in Asia and then migrated to Northern America during the Late Paleocene, and Early-Middle Eocene epochs of the Cenozoic era, about 50-63 million years ago, replacing an earlier pantodont called Barylambda. The first fossil was recovered from Wyoming, in North America. Several other specimens were also found in Europe, Mongolia, and China. The Coryphodon started the ecological space occupied by pigs, camels, cows, rhinos, elephants, and deers. So far, five genera have been grouped with the Coryphodon and about 35 species are under review to be assigned to this genus. Studies revealed that the Coryphodon was not a smart animal. The species had a semi-aquatic lifestyle. Its name is derived from Greek and translates to 'peaked tooth', referencing the angles of its ridges. This creature was incredibly slow as it had short limbs that supported its heavy body.
