Kronosaurus was a pliosaur that lived in the Early Cretaceous of Australia. It was among the largest pliosaurs, and is appropriately named after the leader of the Greek Titans, Cronus. It had an elongated head, a short neck, a stiff body propelled by four flippers, and a relatively short tail. Current estimates put Kronosaurus at around 9–10 meters (30–33 feet) in length.
Kronosaurus never appeared in any films or novels, though it was planned for an early pitch for Jurassic Park IV. It was presumably replaced with the Mosasaurus that appeared in Jurassic World.
It appears as No.118 of the Carnivore Threes in Jurassic Park III: Park Builder.
Kronosaurus appears in the underwater park update for the game Jurassic Park: Builder. Its the third aquatic creature in the park.
