was a semi aquatic lizard with an extremely elongated body that
features a laterally compressed tail around twice the length of the
body. Pontosaurus is so snake-like that it is

record. Additionally semi aquatic lizards similar to Pontosaurus
thought to have given rise to the mosasaurs of the late Cretaceous.
Pontosaurus was originally named as Hydrosaurus, but this had already been used to name a genus of agamid lizard.
