Fine structure of fossilized bacteria in Volyn kerite.
Ultrathin sectioning and cryofracture of fibrous kerite, sampled from 1.8-1.75 billion year old Volyn sediments (Ukraine), revealed in bacteria-like bodies the presence of structures similar to sheath, cell wall, periplasm, cytoplasm, septum, membranes, intramembrane particles, poly-beta-hydroxybutyrate inclusions. On the strength of these data and also the fatty acid profiles of these microfossils, we concluded that fibrous kerites are biogenic formations, namely fossilized bacterial mats.
