An article published in the journal “Science” reports the discovery of a fossil deposit dating back to about 518 million years ago in the southern China’s Hubei province. A team of researchers already led the excavation of 4,351 separate fossils representing 101 species of which 53 are new. The characteristics of the deposit are similar to those of the famous Burgess Shale in Canada and the Chengjiang deposit in China, where fossil conservation is of high quality. These organisms of what has been called Qingjiang biota date back to the period known as the Cambrian explosion and will help to better understand that diversification. Allison Daley of the University of Lausanne published in “Science” a second article concerning the work of the researchers in China.
