Where: Hubei, China (30.8° N, 111.2° E: paleocoordinates 38.7° N, 161.9° E)

• outcrop-level geographic resolution

When: Shibantan Member (Dengying Formation), Ediacaran (635.0 - 541.0 Ma)

• Part of the Sinian System. Paracharnia dengyingensis found 400 meters above the Nantuo tillite and 500 meters below the small shelly fossil assemblages in the lower Tianzhushan Member. The Shibantan Member is 148 meters thick.

• member-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, black limestone and chert
