Yuanmou formation, third member, upper part, Shangnabang (Pleistocene of China)

Also known as Yuanmo formation

Where: Yunnan, China (24.9° N, 100.9° E: paleocoordinates 24.8° N, 100.8° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: third Member (Yuanmou Formation), Pleistocene (2.6 - 0.0 Ma)
