發現: Omeisaurus was named in 1939 by Chinese paleontologist Yang Zhongjian (also known as C. C. Young) based on fossils found in Sichuan, China. The first fossils were collected in 1936 by Charles Lewis Camp and Yang Zhongjian.2 5
仍有爭議: Scientists are not sure whether all Omeisaurus species belong in the same genus. Some studies suggest that Omeisaurus maoianus might be more closely related to Mamenchisaurus.2
