       Pantosaurus was originally described as Parasaurus,‭ ‬however this name had already been used to name a genus of Pareiasaur.‭ ‬Pantosaurus is a genus of plesiosaur that lived in North America during the late Jurassic.‭ ‬Pantosaurus has been noted as having a strong similarity to Muraenosaurus which is known from England and France,‭ ‬though there are clear differences in the humerus and radius‭ (‬two bones of the fore limb‭)‬.
