Beyond the game
The real Tylosaurus
It was a large predatory mosasaur with several recognized species. Its remains have been found on both sides of the Atlantic, helping reveal the variety of these marine lizards.
Its early study was shaped by the rivalry between paleontologists Cope and Marsh as well as by the discoveries themselves. Fossils on both sides of today’s Atlantic reveal its wide distribution.
Mosasaurs were squamate reptiles adapted to the sea. Aquatic life produced streamlined bodies, but did not turn them into fish.
