Say hello to: CAMARASAURUS

CAMARASAURUS (KAM-ah-rah-sawr-us) "Chambered Lizard" (Greek kamara = chamber + sauros = lizard, referring to the holes in its vertebrae)

The most common SAUROPOD in North America during Middle and Late Jurassic times. It also lived in Europe, where it survived into Early Cretaceous times. Camarasaurus was one of the smallest sauropods. Its neck was shorter, and its TAIL was much shorter, than the tails of other sauropods. Camarasaurus grew to be 30 to 60 feet (9 to 18m) long and 15 feet (4.6m) high at the hips. There were holes in the vertebrae to lighten the weight of the backbone. Its forelegs were nearly as long as its hind legs, making the back almost level. The head of this plant eater was larger and shorter than those of most sauropods. Many skeletons of this dinosaur have been found in the western United States. A complete skeleton of a 17 foot (5.2m) long juvenile in nearly perfect condition was found in Utah.
