The weathering crusts are markers of continental sedimentation. The question of land colonization by bacteria is interesting in itself and studies in this field are rather fruitful. An active role of bacteria in the for� mation of ancient weathering crusts has already been shown and land colonization by bacteria is proposed to start at the onset of the formation of sedimentary rocks, i.e., at the very beginning of the geological record (1-3). In the summer of 2007, within the framework of the… 

The Biostratigraphic Paradox of Precambrian Cyanobacteria: Distinguishing the Succession of Microfossil Assemblages and Evolutionary Changes Observed among Proterozoic Prokaryotic Microorganisms

Precambrian cyanobacteria demonstrate unprecedented evolutionary conservatism and have remained practically unchanged for the last 2 Ga, considering that ancient forms have counterparts among genera

Archean Fossil Microorganisms

The article discusses materials on the Archean (4.0–2.5 Ga) microfossils of the Earth (Greenland, Australia, South Africa, and Fennoscandian Shield). The main emphasis is on the description of the



Bacterial-Paleontological Study of Early Precambrian Weathering Crusts

Existence of diverse microorganisms, bacteria (? Cyanobacteria) in the Early Precambrian (Archaean and Early Proterozoic) weathering crusts is determined. Presence of eukaryots can’t be excluded

The evolution of the early precambrian geobiological systems

Bacterial paleontology provides vast opportunities for the study of all types of sedimentary and volcanic-sedimentary rocks, at any stage of metamorphism and of any age. Bacteria are shown to play an
