Abstract
Microfossils and problematics from the Upper Ediacaran deposits of the Zuun-Arts Formation of the Zavkhan Terrane of Western Mongolia are discussed. For the first time, various organic remains preserved in mineralized and organic-clay taphocenoses have been described from these deposits. Numerous tubular microfossils are interpreted as remains of the sheaths of the giant sulfide-oxidizing Thioploca bacteria Candidatus Marithioploca araucae. Autochthonous and allochthonous components of the microbiota were identified, and the possible depositional-ecological environment of the paleobasin was reconstructed.
期刊介绍：
Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
