More sauropods

Short skull The short and high skull of Camarasaurus has a very large orbit (eye socket) and naris (nostril socket). There are approximately 48 spoonlike teeth.

Scientists used to think that the ankylosaurs were the only armored dinosaurs. But the discovery of Saltasaurus proved that some sauropods had armor, too. It was also thought that sauropods may have lived in water, but we now know that the high water pressure at depth would not have allowed them to breathe.

Saltasaurus

At 39 ft (12 m) long, Saltasaurus was quite small for a sauropod. Its armor consisted of large bony plates surrounded by smaller bony nodules. The armor possibly covered Saltasaurus' back and sides. The group of armored sauropods is called the titanosaurids.

Segnosaurus This sauropod was an unusual dinosaur. It does not look like a sauropodomorph, and some scientists place it in a group by itself. Although --■ Segnosaurus ate plants, it may also have eaten meat. Its hands had long, curved claws which it may have used to scratch at termite mounds.

Cetiosaurus An early sauropod, Cetiosaurus had massive, heavy, and solid. Later sauropods had bones that were light and hollow.

Nodules

Only randomly scattered nodules of Saltasaurus have been found, so we can only guess at their position on its body.

Bony lumps

Skin impression Parts of the body of Saltasaurus were protected by a covering of tightly packed, pea-sized, bony lumps
