| The fossilised footprint was left by a lizard called dicynodonts, which roamed the earth before the dinosaurs. |
| The skull is an example of convergent evolution with some of the ornithopods and also with the dicynodonts, an herbivorous group of early synapsids. |
| The dicynodonts as a whole lasted some 50 million years, and the only group of therapsids to outlive them were the cynodonts, which were the direct ancestors of the mammals. |
| One group of therapsids, the dicynodonts, were herbivores with a worldwide distribution. |
