Tylosaurus had a long, bony snout that stuck out like a prow, which is why one species is named proriger, meaning 'prow-bearing'.1

Fossils show Tylosaurus fought each other, with bite marks on skulls and other bones.1

One Tylosaurus skeleton had the remains of a 2-meter-long mosasaur, a diving bird, a fish, and a shark all in its stomach at once.1

Tylosaurus had an endothermic (warm-blooded) metabolism, unlike most modern lizards and snakes.1

It gave birth to live young, not eggs, based on its close relatives.3

Tylosaurus lived from about 93.9 to 66 million years ago, during the Late Cretaceous.3
