YANGTZIRAMULUS ZHANGI NEW GENUS AND SPECIES, A CARBONATE-HOSTED MACROFOSSIL FROM THE EDIACARAN DENGYING FORMATION IN THE YANGTZE GORGES AREA, SOUTH CHINA
Very few macroscopic Soft-bodied Ediacaran fossils are hosted in carbonates: most of them are preserved as casts and molds in siliciclastic rocks or as carbonaceous compressions in black shales. This taphonomic bias limits our capability to fully understand the diversity and paleoecology of macrosco...
