Omeisaurus is of the Sauropoda group. Partial fossils including a head have been found in Mount Emei , China . Even though the fossils have been in very good shape there seems to be a fair bit of identity problems with the dinosaur. Many are thinking that it is made from existing dinosaurs. Through a study in 1996 two scientists claim the Omeisaurus is actually from the family of Mamenchisaurus and particularly a Zigongosaurus. Also another issue with the identity problem is their was a major rumor that Omeisaurus had a club at the end of its tail despite Paleontologists never even found a fossil that showed evidence of this. Apparently one was found near the area that the Omeisaurus was found and they figured it belonged. Changes are a club would've been too heavy ended for this dinosaur and make it very off balance.
The Omeisaurus long neck and round body just like many Sauropods. The only really unique feature was that its nostrils faced forward as opposed to other dinosaurs of the same group such as the Brachiosaurus.
