Reduction spheroids preserve a uranium isotope record of the ancient deep continental biosphere
Red beds contain reduction spheroids that formed underground millions of years ago and whose origin remains poorly constrained. Here the authors use uranium isotopes to identify ancient fingerprints of bacteria in these features, confirming that they were produced by subsurface life in the geologica...
