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. 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.
