A mosasaur was not a dinosaur, but rather an ocean-dwelling serpentine marine reptile more closely related to snakes than to monitor lizards (Lee 1997). These predators evolved from terrestrial ancestors in the early Cretaceous and dominated the oceanic food chain during the late Cretaceous Period.
