       As far as cynodonts go Tritylodon was fairly unremarkable and very similar to the generic form of other cynodonts.‭ ‬Tritylodon had a round body and short limbs,‭ ‬adaptations for a burrowing lifestyle.‭ ‬Furthermore Tritylodon is noted for having enlarged incisor teeth which still would have been partly visible when the mouth was closed,‭ ‬and like relative tritylodontid genera,‭ ‬Tritylodon is thought to have been herbivorous.
       At the time of writing Tritylodon is only known from South Africa and Lesotho.‭ ‬At least one specimen of Tritylodon is known from the Lower Elliot Formation,‭ ‬placing the earliest appearance of the genus in the late Triassic,‭ ‬while most of the known specimens of Tritylodon are currently known from the Upper Elliot Formation which suggests that the genus became far more widespread during the early Jurassic.‭ ‬Additional remains possibly from the Sinemurian and Pliensbachian further show that as a genus Tritylodon was quite successful.
