       Superficially,‭ ‬Pareiasaurus is very similar to its relative Scutosaurus.‭ ‬The main differences between the two are the way the legs support the body.‭ ‬In Scutosaurus the legs are directly underneath the body,‭ ‬giving it a much taller appearance.‭ ‬The legs of Pareiasaurus however came out from the sides in a more familiar reptilian fashion like todays lizards.‭ ‬This means that Pareiasaurus would have carried itself nearer to the ground than Scutosaurus suggesting a specialisation in feeding off very low growing vegetation.‭ ‬A further adaption for a herbivorous lifestyle,‭ ‬Pareiasaurus had leaf shaped teeth and a toothed palate to grind vegetation against.
