Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Doushantuo Formation is a Lagerst tte in Guizhou Province, China that is notable for being one of the oldest fossil beds to contain highly preserved fossils. The formation is of particular interest because it appears to cover the boundary between the problematic organisms of the Ediacaran geological period and the more familiar fauna of the Cambrian explosion of lifeforms whose descendents are recognizable. Taken as a whole, the Doushantuo Formation ranges from about 590 Ma at its base to about 565 Ma at its top, predating by perhaps five million years the earliest of the 'classical' Ediacaran faunas from Mistaken Point, Newfoundland, and recording conditions a good forty to fifty million years before the Cambrian explosion. The whole sequence sits on an unconformity with the underlying Liantuo Formation, which is free of fossils, an unconformity usually being interpreted as a period of erosionshow more
