RETURNING: Mosasaurus

Technically the Mosasaurus, onetime star of Jurassic World’s signature water show, is not a dinosaur, but a lizard. That does not make her one iota less ferocious than the other inhabitants on Isla Nublar, or in Mosa’s case, off its coast. The Mosasaurus has two sets of teeth, including a second in her upper palate that makes the journey down her down into her belly that much less pleasant.
