Hypercoryphodon (SciiFii)

Hypercoryphodon is a genus of rhinoceros-sized pantodont native to Late Eocene Mongolia, and was very similar to its ancestor, Coryphodon. Described from a skull, Hypercoryphodon is a quadrupedal hippopotamus-like herbivore that may have been able to adapt its feeding to suit different situations. It is thought to have possibly lived in wetland to forest ecosystems that it might have shared with other herbivores such as dinoceratans like Gobiatherium.[2]
