How were sauropods armoured?

 

                  Most of the great sauropods relied on their huge size to prevent attacks from predators. Saltosaurus was not as large as many of the other sauropods, but as compensation for this its back was covered with armoured plates. These plates were ridged and packed close together to provide extra protection. The fossils of Saltosaurus found so far are incomplete, so we do not know exactly how far this armour extended over its body. Most of the sauropods were well able to defend themselves with a large clawed toe on the inside of the front foot, and they probably also trampled any attackers, using their great weight.
