Omeisaurus > Omeisaurus changshouensis (Young, 1958) > Omeisaurus fuxiensis (Dong, Zhou & Zhang, 1983) > Omeisaurus tianfuensis (He, Li, Cai & Gao, 1984) > Omeisaurus luoquanensis (Li, 1988) > Omeisaurus maoianus (Tang, Jin, Kang & Zhang, 2001) > Omeisaurus jiaoi > (Jiang, Liu, F., Peng & Ye 2011)

Introduced in a paper by He, Cai, Li, and Gao in 1984, Omeisaurus tianfuensis is known from deveral incomplete skeletons that have been assembled into a complete individual.The composite skeleton is 20-meter-long. Several skulls in various degrees of preservation are known, but unfortunately none has been found articulated with a neck.

He, li and Cai authors of a new (1988) Omeisaurus tianfuensis monograph, however, are confident that they have associated the skulls with the proper skeletons. Almost ten meters long and comprising the usual 17 vertebrae, the neck of Omeisaurus tianfuensis is second only that of Mamenchisaurus hochuanensis in size.
