VERIFY:geological_stage: stored=middle to late jurassic suggested=Middle Jurassic (Bathonian–Callovian) confidence=medium — Current peer-reviewed work places the Omeisaurus-bearing lower Shaximiao Formation in the Middle Jurassic, with the unit described as deposited in the Bathonian to Callovian and a tuff zircon U-Pb weighted mean age of 166.0 ± 1.5 Ma. Extension of the stage into the Late Jurassic is no longer supported, since Upper Shaximiao (Late Jurassic) material referred to Omeisaurus is now generally regarded as indeterminate.
