Moanasaurus

Moanasaurus (From Māori "moana" "sea" and Greek "sauros" "lizard"; meaning "Sea Lizard") was a genus of mosasaur from the Late Cretaceous period. Its fossil remains have been discovered in the North Island of New Zealand. "Moanasaurus" was a very large mosasaurine known originally from a disarticulated skull, vertebrae, ribs and flipper bones. It reached 12 m in length and the skull is 78 cm, which shows that "Moanasaurus" was one of the largest in the subfamily of Mosasaurinae.
