Extended Data Fig. 7: Ocean redox data for EBA-1.

The dashed line on the Fe/Al plot represents the upper boundary for distinguishing anoxia37 and on the FePRS/Al plot the Phanerozoic average68. Dashed lines on the FeHR/FeT and FeHR*/FeT plots distinguish oxic and anoxic deposition38. Dashed lines on the FePRS plot represent the average Phanerozic range (1.80 ± 0.85 wt%; 1σ)68.
