Hainosaurus is a member of the mosasaur family, a group of aquatic reptiles related to lizards that lived during the Cretaceous period. It was one of the largest members of its family. In a paper published in 2016, Hainosaurus was considered congeneric with Tylosaurus, but not everyone is convinced.
Hainosaurus can be created in Jurassic Park: Builder in the Aquatic Park section of the game.
Hainosaurus appears in the underwater section for the game Jurassic World: The Game as a VIP surface creature.
