Prehistoric deep-sea behemoth 03: sauropod, also known as Kenosaurus and sauropod, is a kind of marine reptile, belonging to plesiosaur suborder, and its obvious feature is short and thick neck. Contemporary animals include a large number of fish and various mollusks, such as squid, ammonite and arrow stone.
Some fossils of the above animals, the tooth marks on the carapace may be caused by Crosaurus, and their back teeth are round, which is suitable for crushing animals with hard shells. Once in the Albian strata of Australia, a large round tooth mark was found in the Tuarangisaurus fossil of Leptosaurus, which should have been attacked by Crosaurus.
