What were sauropods?

 

                   Sauropods were a group of dinosaurs that were all built to the same general design. They all had a short barrel – shaped body to accommodate the huge gut needed to digest their vegetable diet, a very long neck and tail, a comparatively tiny head and peg-like teeth for grazing. The other important feature of the sauropods is that they were all enormous. They were extremely heavy, and because they lived in large herds they churned up the ground as they moved about. It is still possible to see the damage caused by their movements in the ancient rock layers where fossils of the sauropods have been found.
