Thadeosaurus | |
Thadeosaurus is an extinct genus of diapsid reptile belonging to the Order Eosuchia. Fossils have been found in Madagascar, and date to the late Permian period.
Thadeosaurus was a lizard-like animal, with a remarkably long tail that comprised about two thirds of the animal's total length of 60 centimeters (2.0 ft). It also had long toes, especially on the hind legs, which would have given it a powerful stride, since the toes would still touch the ground while the foot was being raised. Coupled with a strong breast bone to increase the strength in the forelimbs, this means that Thadeosaurus was probably a good runner.[1]
