Similarly, Megalneusaurus was a distinct carnivore marine reptile that belonged to the family of a pliosaur. From the remains of the specimen that has been discovered, it is inferred that the species belonged to the Late Jurassic period.The genus Megalneusaurus consists of only one type species, Megalneusaurus rex, and their identification is generated by pieces of the ribs, pectoral girdle, fore-paddle, and vertebrae. Another specimen that was discovered from southern Alaska has been considered as Megalnesaurus which is smaller in size.
