Thrinaxodon

Extinct genus of cynodonts

Thrinaxodon is an extinct genus of cynodonts which lived in what are now South Africa and Antarctica during the Early Triassic. The genus contains a single species, T. liorhinus. Similar to other therapsids, Thrinaxodon adopted a semi-sprawling posture, an intermediary form between the sprawling position of basal tetrapods and the more upright posture present in current mammals.
