ANATOMY
Camarasaurus was a long-necked, long-tailed giant herbivore, measuring about 24 to 65 feet (7.5 to 20 m) long 15 feet (4.6 m) tall at the hips, and weighing up to 20 tons (roughly 28000 kg). It 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 a long, 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.
