| Abstract: | Ultrathin sectioning and cryofracture of fibrouskerite, sampled from 1.8–1.75 billion year old Volynsediments (Ukraine), revealed in bacteria-like bodies thepresence of structures similar to sheath, cell wall,periplasm, cytoplasm, septum, membranes, intramembraneparticles, poly- -hydroxybutyrate inclusions. On thestrength of these data and also the fatty acid profilesof these microfossils, we concluded that fibrous keritesare biogenic formations, namely fossilized bacterial mats. |
