Abstract

The conjecture that bacteria, or, more widely microbes are capable ofbemg preserved like large organisms as fossils seemed very improbable as late as the 1960's. Reports ofbacterial remains discernible in sedimentary rock were invariably called into question.There were substantial grounds for that: bacterial morphology is normally little expressed, and cocci or micron-sized bacilli can be easily imitated by mineral formations. An exception was made for flint rock, primarily silicified parts of stromatoliths.
