The rangeomorph fossil Charnia from the Ediacaran Shibantan biota in the Yangtze Gorges area, South China
terminal Ediacaran Shibantan biota (-550-543 Ma) from the Dengying Formation in the Yangtze Gorges area of South China represents one of the rare examples of carbonate-hosted Ediacara-type macrofossil assemblages. In addition to the numerically dominant taxa & mdash;the non-biomineralizing tubul...
