Dengying Formation

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

Members
Listed by ascending age:
 * The Hamajing Member is characterized by light grey, medium- to thick-bedded dolomite, intercalated with thin layers of chert.
 * The Shibantan Member is interpreted to represent a subtidal environment and is composed of dark grey, thin-bedded bituminous limestone. It is the most fossiliferous of the Dengying Formation members and has yielded several trace fossils, such as Lamonte, as well as possible lobopodian trackways.
 * The Baimatuo Member consists of light grey, thick-bedded dolomite.

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.
