The dinosaurs dominated the Earth for over 165 million years during the Mesozoic Era, but mysteriously went extinct 65million years ago.

CAMARASAURUS the "Chambered Lizard".

This dinosaur was much smaller than its fellow sauropods. It had a small, long head with a blunt snout and spoon-shaped teeth. Its neck and tail were shorter than most other sauropods. It had thick legs with five-toed feet; the inner toe had along, sharp claw for protection. The front legs were only a bit shorter than its back legs, making its back almost level to the ground. Its name, "chambered lizard," comes from the holes in its vertebrae that decrease its weight
