Stomatolites: maybe they aren't so old | Helder, MJ. 1985.
CS Dialogue 12(2):5-6. CELD ID 13239Abstract It was in 1954 that the tiny hamlet of Schreiber on the northern Ontario shore of Lake Superior achieved a certain degree of fame in the geological world. In that year a field biologist and a palaeobotanist (Tyler and Barghoorn, respectively) reported the remains of microorganisms in strangely layered rock called chert. Identified as bacteria and blue-green algae, the well-preserved microorganisms were hailed as "the most ancient organisms known".
