Because of their complexity, postcanine teeth are the primary means of identifying and distinguishing different species of traversodonts. 1349:

Traversodonts have relatively short skulls. The snout is much narrower than the back of the skull. The tip of the snout is wider than the middle, as it constricts behind the large canines. The tooth rows of the upper jaws are inset while the
