Doushantuo Formation

The Doushantuo Formation is a famous fossil-bearing rock layer in China, dating back about 600 million years. It contains some of the earliest known microscopic life, including tiny fossils of early animals and algae. These fossils provide crucial insights into the origins of complex life on Earth during the Precambrian period. The formation is valuable to scientists because it helps them understand how life evolved before the rise of large, complex organisms. Its well-preserved fossils make it a key site for studying early biological history and the conditions of ancient Earth.
