Tillodon is a genus of tillodont from Eocene North America. [1]
Tillodon had a large skull and teeth, with a deep and thick jaw. The molars are brachydont. The premaxilla of Tillodon makes up a majority of the skull's size. [2] Tillodon has been compared to rodents due to enlarged incisor teeth, which (alongside the related Trogosus ) has caused the genus to be erroneously considered the ancestors of the rodents . [3]
Tillodon is known from the lower Bridger formation, and lived alongside many artiodactyls, such as homacodonts, perissodactyls like the early brontothere Telmatherium, dinocerates like Uintatherium and early carnivorans like Uintacyon. [4] Tillodon most likely ate tubers and roots, much like other tillodonts. [5]
