Omeisaurus is now known from most parts of the skeleton including the skull. Omeisaurus is most closely allied to, and perhaps a descendant of Datousaurus. Among the several species, Omeisaurus junghsiensis and Omeisaurus tianfuensis are most complete known.

The skull most nearly resembles that of Shunosaurus bit is relatively shorter and higher, and the supratemporal fenestra is larger.
