Paleontologists have discovered the exceptionally well-preserved, 3.42-billion-year-old filamentous microfossils in a paleo-subseafloor hydrothermal vein system in what is now South Africa; the filaments colonized the walls of conduits created by low-temperature hydrothermal fluid; combined with their morphological and chemical characteristics.
They can be considered the oldest methane-cycling microorganisms, most likely methanogens.
