Pontosaurus

Pontosaurus is a now extinct genus of pythonomorph from the Late Cretaceous period. It was originally named Hydrosaurus, but that name was preoccupied by an agamid lizard, so it was renamed. It is known from two species, both Cenomanian in age, the type P. lesinensis which is known from Hvar in Croatia, the other P. kornhuberi is known from the Sannine Formation in Lebanon.[2] Both species were relatively small. P. krohuberi reached 1 m (3.3 ft) in length and 1.1 kg (2.4 lb) in body mass, while P. lesinensis reached 1.2 m (3.9 ft) in length and 2 kg (4.4 lb) in body mass.[3]
