Fossils of Cengjiang Biota (National Museum of Natural Science)Type Collection Collection Identifier c0320 Description The Chengjiang biota was first discovered in the yellow-green shales in Maotienshan in Chengjiang County, Yunnan Province. In recent years, however, abundant Chengjiang biota fossils were also found in the siltstone layer above the shales, their known geographical distribution also expanded to the eastern areas in Yunnan. As more and more scholars joined the relating research, it was discovered that the Chengjiang fossil groups of different areas differed due to their burial conditions. Because the Chengjiang biota preserved many soft-bodied beings, it has attracted many scholars at home and abroad to join the research, and investigate the causes for the appearances of differents groups. In addition to the diatom fossils, sixteen animal phyla and more than ten unconfirmed species fossils have been discovered. The Chengjiang biota has become the earliest geological record of most known, existing animals, due to its diversity and the fact it is ten million years older than the Burgess Shale.
