The Dengying Formation is an upper Ediacaran (551-541 Ma[1]) fossiliferous geologic formation found in South China. It was deposited on a shallow marine carbonate platform.[2]

Members

Listed by ascending age:

  • The Hamajing Member is characterized by light grey, medium- to thick-bedded dolomite, intercalated with thin layers of chert.[2]
  • 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.[3]
  • The Baimatuo Member consists of light grey, thick-bedded dolomite.[2]

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.[2]
