Tylosaurus proriger was actually the proper creature in the Evolution's Winners episode of Dinosaur Revolution.

Parental CareEdit

Tylosaurus may not been a caring parent, as seen in the episode although it is debated at the time. Tylosaurus may have lived alone and it almost certainly could harm an animal like Archelon. 

Evolution's Winners Edit

A mother tylosaurus is seen swimming giving birth to live young in the deep ocean when a pack of three hungry squalicorax start attacking the young leaving only one to successfully breach and hide from the deadly sharks. The mother tylosaurus attacks one of the sharks by ramming into it at 48 kph and easily kills it. The two other sharks try to swim away from the deadly mosasaur but it seizes a shark and tears it apart. The tylosaurus spots the last shark and charges at it easily destroys it. The mosasaurs young eats the rest of it's kill and the mother tylosaurus breaches.
