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 dolostone, 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 dolostone.〔 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Dengying Formation」の詳細全文を読む スポンサード リンク
