Short summary
Mild eruption of hydrothermal solutions on deep-sea benthic floor can produce anhydrite crystal layers, where microbes are trapped and preserved for a long period of time. These embedded original inhabitants will be biomarkers for the environment when the hydrothermal eruption occurred. This study discovered a thick anhydrite layer in a deep-sea brine pool in the Red Sea. Oil-degrading bacteria were revealed in the crystals with genomic and microscopic evidence.
