  • Pliosaur

    Pliosaurs were aquatic carnivorous reptiles, not dinosaurs, that lived between 220 and 70 million years ago. This pliosaur has not yet been named scientifically but may be a specimen of Yuzhoupliosaurus chengjiangensis.

  • Kronosaurus queenslandicus

    Kronosaurus queenslandicus, from the Early Cretaceous of Queensland, was the largest known pliosaurid. These huge marine carnivores plied the oceans and inland seas during the Mesozoic, using both pairs of limbs to 'fly' underwater. Kronosaurus would have hunted large fish, invertebrates such as giant squid and ammonites, and perhaps even other large reptiles like elasmosaurids and ichthyosaurs.

  • Umoonasaurus demoscyllus

    Pliosaurs are actually aquatic carnivorous reptiles, not dinosaurs. 'Eric' was a small, short-necked pliosaur and and was discovered by an opal miner in Coober Pedy in 1987. 'Eric' is one of the most complete opalised vertebrates known and became part of the fossil collection of the Australian Museum in 1993 after money to purchase the specimen was raised by the schoolchildren of Australia (with the help of Akubra Hats). 'Eric' is currently on display at the Australian Museum.
