Dicynodonts

Dicynodonts are therapsids with beginnings in the Mid-Permian, which were dominant in the Late Permian, survived the Great Dying that wiped out most other therapsids and continued on throughout the Triassic before dying out at the end of the period. Dicynodonts were herbivorous animals with two tusks, hence their name, which means 'two dog tooth'. They are also the most successful and diverse of the non-mammalian therapsids, with over 70 genera known, varying from rat- to elephant-sized.
