Geothermal environments are hotspots for carbon cycling. Here, De Anda et al. reconstruct archaeal genomes from terrestrial and deep-sea geothermal sediments, and propose the classification of these microbes as a new phylum, āBrockarchaeotaā, with unique metabolic capabilities including non-methanogenic anaerobic methylotrophy.
