Middle Jurassic ammonites collected in situ from the Lanongla sections, Lanongla, South Tibet allow the precise dating of the ferruginous Oolite beds and the underlying limestone beds in this area. A large hiatus of 8 million-year duration in South Tibet is well documented by the ammonite succession. Revision of sea-level changes curve in Tibet during the Middle Jurassic is proposed; the high sea-level stands below and above the disconformity are dated as Humphriesianum Zone (late Early Bajocian) and Orbis Zone (early Late Bathonian), respectively
