Oldest known archaea microbes? (Barberton greenstone belt, South Africa)
Oxytropidoceras posted a topic in Fossil News
3.42-billion-year-old fossil threads may be the oldest known archaea microbes. The structure and chemistry of the filaments hints that they may be ancient cells. By Carolyn Wilke, Science News, July 26, 2021 Cavalazzi, B., Lemelle, L., Simionovici, A., Cady, S.L., Russell, M.J., Bailo, E., Canteri, R., Enrico, E., Manceau, A., Maris, A. and Salomé, M., 2021. Cellular remains in a~ 3.42-billion-year-old subseafloor hydrothermal environment. Science Advances, 7(29), p.eabf3963. Yours, Paul H. -
