Chengjiang Fossils

The Maotianshan Shales, alson known simply as Chengjiang ranks as one of the most important Lagerstätten fossil sites in the world. The Chengjiang site is located in the Yunnan Province of China in the villages of Ercaicun and Chengjiang near the city of Kunming. Some 50 meters of mudstone sediment are exposed, yielded many excellently preserved soft-bodied creatures of the Cambrian Explosion. Dated at 525 million years ago, it lies just above the Precambrian-Cambrian boundary at 544 million years ago.
