Earth-like soils on Mars? Ancient fossilized soils potentially found deep inside impact crater suggest microbial life -- ScienceDaily
This out recently from the same scientist that reinterpreted the Ediacaran fauna as terrestrial lichens, fungi and biocrusts, http://geodermatophilia.blogspot.com/2012/12/very-early-life-on-land-just-who-is.html
A networking resource devoted to biological soil crusts and the researchers who study them. We will provide a means for international scientists to communicate, share their research, share important news and announcements, ask questions and find collaborators. We will also provide a space for informal writing on research, opinion, and ideas (now seeking posters!).
