Order: Squamata
Family: Varanidae
Length: 13 meters

Diet: Fish and marine reptiles
Age and Location: Late Cretaceous, 70 million years ago, worldwide

The first mosasaur ever found. Caused a large media frenzy when it was found in the Netherlands.

The squamata is almost twice the weight of the crocodilian. If it kills one of the crocs quickly, the other one stands little chance.

Well, it does depend on how fast 1 Deinosuchus is killed.
I think the Mosasaurus would have a slight edge but the gators aren't to be underestimated, since they could mob it and inflict severe damage.

Mosasaurus is much bigger than both Deinosuchus combined and has better water adaptations, it will win here.
