Dicynodon ("Two Dog-teeth") is a type of dicynodont therapsid that flourished during the Late Permian period. Like all dicynodonts, it was herbivorous. This animal was toothless, except for prominent tusks, hence the name. It probably cropped vegetation with a horny beak, much like a tortoise, while the tusks may have been used for digging up roots and tubers.
Many species of Dicynodon have been named, and the genus is considered a wastebasket taxon. A 2011 study of the genus found most of the species to represent a paraphyletic grouping, with the only valid members of Dicynodon being D. lacerticeps and D. huenei.

Another extinct amphibian and another wrong guess is next: Dicynodon, portrayed as a massive critter with a turtle-like shell and two big jutting fangs.
In fact Dicynodon looked more like a hippopotamus than a turtle, but give the sculptor high marks for imagination.
