The Dengying Formation is an upper Ediacaran (551-541 Ma[2]) fossiliferous geologic formation found in South China. It was deposited on a shallow marine carbonate platform.[3]

Members

Listed by ascending age:

Traditionally, the Tianzhushan Member was considered to be the uppermost unit of the Dengying Formation. However, its small shelly fossils and Micrhystridium-like acritarchs are a shared characteristic with the Cambrian Yanjiahe Formation.[3]
