Rhoetosaurus is a kind of dinosaur genus existed in the late Bajocian of the Jurassic period, over 154 to 180 million years ago. It is believed that those species are the inhabitants of current Australia. Rhoetosaurus belongs to the group of sauropod. This herbivore species comes under the classification of Chordata, Reptilia, Dinosauria, Saurischia, Sauropodomorpha, Sauropoda.
Heber Longman was the first to describe and name the species in 1926. Series of 16 consecutive bones with fragmentary hind limb pieces were initially discovered collating a collection of 22 tail vertebrae. From the skeletal structure it has been observed that the creature had a gigantic figure estimated about12-15 meters long. Later some body parts of thoracic area, bits of rib, caudal, femur and pelvis have been added to the skeletal structure. This skeletal specimen is still kept in display at Queensland Museum.
