Abstract

The biostratigraphical significance of individual taxa of Precambrian micro-organisms has been considered. The results of an analysis of the morphological variability of ancient colonial forms are comparable to present-day coccoidal cyanobacteria of the Gloeocapsa Kutz. genus. Conclusions have been made on the origin, nature, and direction of changes in the Gloeocapsa-shaped colony composition as well as on an opportunity to use them for biostratigraphical purposes.
