The Chengjiang Biota

The Chengjiang biota was discovered by Hou Xiang-guang in 1984 and is famous for exceptional preservation of a host of exquisitely preserved soft-bodied organisms. The 525 Ma deposit is located in Yunnan Province, China and contributes fundamentally to our understanding of one of the most important evolutionary episodes in the Phanerozoic – the Cambrian evolutionary  ‘explosion’. Well over 200 species across at least 16 phyla have been recognised in the Chengjiang biota and most are exclusive to this deposit.

I have visited the field localities of the Chengjiang biota on several occasions and worked with Chinese colleagues at the Key Laboratory for Palaeobiology (Yunnan University) on their incredible fossil collections. My research on this Lagerstȁtte has mainly involved investigation of the taphonomy of the fossils and the sedimentology and geochemistry of the host shale. I also undertake work to interpret anatomy, affinity and ecology of fossils from the Chengjiang.

The Team

I am a member of an extensive team of scientists principally from China and the UK. Based in China at the Yunnan Key Laboratory for Palaeobiology, Yunnan University, Kunming are: Professor Hou Xianguang, Dr Cong Peiyun, Dr Qi Changshi. Based in the UK are: at the University of Leicester, Professor David Siveter, Professor Mark Williams, Dr Sarah Gabbott and Professor Mark Purnell; at the University of Oxford is Professor Derek Siveter, and at the Natural History Museum is Dr Ma Xiaoya. I also work with Dr Robert Gaines who is based at Pomona College, USA.
