Orcasaurus- Queen of the seas

The Orcasaur (monster lizard) is a giant amphibious mosasaur of the clade Delphinovaranidae, a group of Mosasaurs that have become streamlined, powerful pursuit predators ranging from 4 to 100 feet long or more. Growing to 120 feet long, it is the largest predator on earth, far bigger than even the mighty land-dwelling Vastatotyrannus rex. Males are smaller than the females and are more likely to be found in small groups. Females are solitary, only breaking their lonely treks across the ocean when they are with a calf. Calves are born alive and on shore, when the gigantic mother hauls herself onto island beaches with her well developed front flippers to keep her baby from being eaten by large sharks or male Orcasaurs. the calf will then stay on the beach and in the shallows as it grows, feeding on fish, smaller sharks, squid, and marine reptiles its mother brings back for it. As adults they will attack virtually any prey that moves from sharks and giant squid to other mosasaurs, and can dive to depths of over 7000 feet. Living as long as 100 years, Orcasaurs have no predators as adults and have learned that to be the top of the food chain in the game of predator and prey, it is best to be entirely the one and never the other.
