When translated to English the Greek name Camarasaurus means "chambered lizard". Camarasaurus was one of the smallest sauropod species, but it was also one of the most common Cretaceous dinosaurs. They spanned most of the Cretaceous. Fossils of Camarasaurus have been in North America, Africa and Asia. An abundance of fossils have been found in the Morrison Formation of southwestern U.S.A. These sauropods grew to approximately 20m in length and weighed up to 25 tonnes.
Unlike most sauropods which had blunt peg-like teeth, Camarasaurus had robust, epatulate(chisel shaped) teeth throughout their mouths. These teeth were designed for chewing which allowed Camarasaurus to devour much tougher vegetation with ease. (Image courtesy of
