Finds of Ediacaran-Type Fossils in Vendian Deposits of the Yudoma Group, Eastern Siberia

摘要

It has been established that terrigenous units of mainly carbonate deposits of the Yudoma Group in the Uchur-Maya Region of the Siberian Platform contain an assemblage of Late Vendian Ediacaran-type macrofossils. The assemblage contains species such as Aspidella terranovica, Beltanelliformis brunsae, Nenoxites curvus, and Palaeopascichnus sp., which had widespread geographic distribution. Finds of Ediacaran fossils in fossil-rich deposits of the Yudoma Group have expanded the possibilities of using the classic biostratigraphic approach applied for subdivision and global correlation of carbonate deposits in Late Precambrian paleobasins.
