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.
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 . == Paleoecology ==
