Rock-eating fungi flourish deep below our feet https://news.umich.edu/rock-eating-fungi-flourish-deep-below-our-feet/
Deep subsurface organic-rich shale supports abundant, diverse, and novel fungi https://academic.oup.com/ismej/advance-article/doi/10.1093/ismejo/wrag184/8744037
"the water was last in contact with the surface 11,000 years ago.
