Abstract：The Ediacaran Miaohe biota is one of the key windows on the evolution and radiation of complex multicellular eukaryotes between the Snowball Earth and the Cambrian Explosion.Recently,several localities of the Miaohe biota have been reported in western Hubei Province,sparking different opinions on its stratigraphic position.In order to better reveal characteristics of the Miaohe biota in different regions/facies,we conducted systematic paleontological analysis on a newly discovered fossil site of the Miaohe biota at the Lianhua section in eastern Shennongjia area.A total of 11 genera and 12 species of macrofossils were identified,including typical fossils previously described in the Miaohe biota,with dominant species being Cucullus fraudulentus,Baculiphyca taeniata and Grypania spiralis.The discovery of the new macrofossil assemblage not only expands the paleogeographic distribution of the Miaohe biota,but also provides significant insights into the evolution of Ediacaran macrofossils in different environments.
