Global Experts Uncover New Cambrian Fossil Trove in Central China's Hunan Province
An international team of over 160 scholars and researchers from China, the United States, Canada, and Russia has concluded joint fieldwork and academic discussions on a newly discovered Cambrian fossil site in Hunan Province, central China. This site, known as the Huayuan biota, has yielded over 50,000 fossil specimens, with 153 identified animal species, nearly 60% of which are new to science. The research, led by CAS academician Zhu Maoyan, was published in the journal Nature earlier this year. The Huayuan biota is chronologically positioned between the peak of the Cambrian explosion (represented by the Chengjiang biota) and the later Burgess Shale, documenting marine life immediately following the Sinsk mass extinction. The Xiangxi region, where the site is located, was a deep-marine slope environment over 500 million years ago, providing exceptional conditions for preserving fine anatomical details of soft-bodied organisms. This discovery challenges previous assumptions that marine life was scarce afte...
