Scutosaurus lived during the Permian Period about 250 million years ago in what is now Europe. Scutosaurus measured 8 feet (2.5 meters) long. It had a similar appearance to Pareiasaurus, to which it was related. Scutosaurus was a slow moving bulky herbivore. It fed on vegetation that floated on surfaces of freshwater lakes. Scutosaurus lived in herds. Its teeth were adapted to easily cut through leaves and stems. The gaps between its teeth suggest that water could freely drain from its mouth, leaving only plant material behind to be chewed. The adults grew a horn on its nose, and spikes pointed down from the jaw. Scutosaurus' body was covered with bony projections perhaps to protect it from predators. These bony projections are found on most of its body.
