Camarasaurus details:

Camarasaurus was a genus of quadrupedal, herbivorous dinosaurs. Camarasaurus have comparatively shorter necks than brachiosaurs, and they have shorter necks and tails than diplodocids. Grew up to fifty feet long, shorter in length than some of its contemporaries like Diplodocus and Apatosaurus, but stood taller. Enough of the rock was removed to reveal the left side of the specimen. Its unusually large chisel- or spoon-shaped teeth equipped Camarasaurs to browse on a wide variety of vegetation. New studies suggest they may have provided nutrients, like calcium, from various minerals.
