Sauropods A-Z

Amargasaurus   A relatively small sauropod from the Late Jurassic. It was 10 metres (33 feet) long, with two rows of tall spines running down its back. These may have supported skin sails which could have acted as temperature controllers. They would also have made it look larger to predators. 

Apatosaurus   A large sauropod from the Late Jurassic. At 23 metres (75 feet) long, Apatosaurus was one of the largest land animals ever. It is often mistakenly called Brontosaurus, after two skeletons of the same species were accidentally given different names. The first to be named was called Apatosaurus, so it kept this name.
