Taphonomy
Modes of preservation:cast,soft parts
Preservation of anatomical detail:good
Articulated whole bodies:some
Associated major elements:some
Fragmentation:occasional
Collection methods and comments
Collection methods:surface (in situ),survey of museum collection
Reason for describing collection:taxonomic analysis
Collection method comments: Fossils represent the first find of genuine Late Precambrian soft body Edicaran in China. The median stems are preserved as infilled casts and the polyp leaves are preserved as black, film-like, organic compressions. Specimens originally described as Charnia dengyingensis by Ding and Chen in 1981.
