  2. RHOETOSAURUS • “Rhoetos” a mythological Greek giant • And saurus meaning Lizard. • Was found in 1925 by a self-trained • Paleontologist named Heber Longman. • It lived 176 to181 years ago • In eastern Queensland whereas • a large reptile fossil was found. • is among the best known • Sauropods thus, far discovered • In australia.

  3. Rhoetosaurus may have weighed 20 tonnes- as much as four elephants. They were quadrupeds (four-footed) and they existed in many parts of the world, probably from about 210 million years ago (at the start of the Jurassic Period) to 65 million years ago (at the end of the Cretaceous Period). its most powerful defensive weapon was its long supple tail. Massive muscles attached to the tail vertebrae, and more supple joints at the base and tip of the tail, allowed the tail to be swept around with great agility and force. Every large animal has to adapt to the problems of weight and Rhoetosaurus was no exception. Its legs had to support the body's weight, and withstand the impact of stepping without the pressure becoming too great for the joint cartilages.

  4. Why is it extinct? Many sauropod dinosaurs lived in the late Jurassic period. They dominated the landscape. There was a minor mass extinction towards the end of the Jurassic period. During this extinction, most of the enormous sauropod dinosaurs died out. No one knows what caused this extinction.
