Extended Data Fig. 7: Model estimates of the burial rates of marine and terrestrial organic carbon from 600 Ma to present45.
From: Carbon/phosphorus burial ratio reveals a rapid spread of land plants during the Late Ordovician

Grey- and green-shaded regions indicate the marine (grey) and terrestrial (green) components, shown as a stacked area chart. Detailed calculation methods and model parameter settings for these estimates are available in the reference cited above.
