Genus information

Thrinaxodon is a genus of cynodont that lived in Africa and Antarctica during the Lower Triassic epoch. Cynodonts belong to a group, called stem mammals and are thought to be the ancestors of all mammals. Thrinaxodon lived just after the Permian - Triassic mass extinction event and its ancestors probably survived by their burrowing habits. It probably fed on small reptiles and invertebrates.
