Taxonomic note
Zavarzin (1981): "The microorganisms of genus Metallogenium comprise a peculiar group of animate creatures that are very important to the manganese cycle. This may be the oldest microorganism to come down to our days unchanged because its fossils under the name Eoastrion (Barghoorn and Tyler, 1965) from the Gunflint formation (more than 109 years ago) do not differ from the present-day specimen." - (17 August 2021) - E.A. Molinari Novoa
