Barosaurus being of the Sauropoda group shares a lot of the same features as many other of the same category. Others that are in this group consist of many very large herbivores such as the Brachiosaurus, Brontosaurus, and others that were very close to identical.
The first Barosaurus fossil was found by Mrs. E. R. Ellerman in 1890. The Fossil was only a part of a tail and was actually collected by Charles Marsh. This was in South Dakota , USA . It wasn't until 1898 a man named George Wieland went back to the site and found the remainder of the full body of the original first Barosaurus ever found. Since then there has been many discoveries in a long list of areas. In 1922, Earl Douglas ran a dinosaur discovery expedition in Utah , because of a previous finding of an Apatosaurus (Brontosaurus). He found 3 near complete skeletons of Barosaurus'.
The name Barosaurus means "heavy lizard". Barosaurus got its name because of its size and it's very long neck. It had a long tail as well. Its total length was roughly 89 feet.
It is very hard to determine the look of the Barosaurus head because there has never been a skull discovered yet. This was very typical for the larger Sauropods because their heads were commonly small for the size of their bodies.
