Paper Abstract

Organic-walled microfossils from two Siberian representative microbiotes of the Neoproterozoic Miroedikha and Lakhanda Formations include mat-building cyanobacteria, accompanied by less common bacteria-like microfossils from the terrigenous rocks. Bacterial remains not so often are mentioned under the study of the organic-walled microfossils. Three morphotypes of microfossils bearing a close resemblance to bactera are discussed. These morphologically simple but complex in physiology organisms had the great importance for the Precambrian biota evolution. The occurrence of Prokaryotes among sufficiently differentiated microfossils of the Upper Riphean allows extrapolating back to the time, when evolutionary innovations had took place in the Precambrian.
