Camarasaurus ( KAM-uh-ruh-SAWR-us)
A quadrupedal sauropod from the Late Jurassic of Colorado, Oklahoma, Utah and Wyoming, USA.
Camarasaurus was heavily built. Its big, blunted head had a short face, big eyes and four dozen big teeth.
Big nostril-openings on the top of the skull indicates, for some experts, that it might have had some sort of trunk.
