Doushantuo Formation

Index Doushantuo Formation

The Doushantuo Formation is a fossil Lagerstätte in Weng'an County, Guizhou Province, China that is notable for being one of the oldest beds to contain minutely preserved microfossils, phosphatic fossils that are so characteristic they have given their name to "Doushantuo type preservation". [1]
