seems to have been more herbivorous given that the teeth and jaw
structure of Exaeretodon seem to be more suited to
interesting point of note however is that very young juveniles had no
teeth. This suggests that young Exaeretodon had
to stay with the
mother for an extended period of time before their adult teeth came in
and they were able to process their own food.
At just under two meters long Exaeretodon was certainly one of the larger cynodonts, though genera such as Diademodon were slightly larger.
