Tylosaurus was a fast-swimming, “ram-snouted” member of the mosasaurs, a group of marine lizards (not dinosaurs) that had rapidly radiated to become the dominant predators in Late Cretaceous seas. While surely possessing a nasty bite, the pointed snout of Tylosaurus is thought to have been used for swimming at high speed into potential prey, stunning them and making them easier to dispatch. The largest Tylosaurus individuals, including the Bruce specimen (MT2) of Tylosaurus pembinensis (shown here) and the Bunker specimen (which was recently given its own species, Tylosaurus rex), grew up to 13 meters (42 feet) in length, and potentially weighing up to 7 tonnes, these were true monsters.
