The Camarasaurus was about 59 feet long and probably weighed about 20 tons. Polished pebbles are often found in the same area as Camarasaurus fossils It is possible that the Camarasaurus may have swallowed rocks to aid in grinding up the tough plant food they ate.

The Camarasaurus would later regurgitate the stones and replace them with new stones once the stones had been worn down and were no longer useful as a digestive aid.


The Camarasaurus was a giant plant eating dinosaur that lived about 155 to 145 million years ago. It is believed that the Camarasaurus was very common during that period and may have roamed in herds over the tropical plains that covered North America during that time.
