Results of the divergence time estimation of 639 taxa of seed plants from the reanalysis of a previously described10 phylogeny. Fossil calibrations are indicated at the nodes with green circles, and numbers correspond to fossils described in Supplementary Table 2. Concentric dashed circles represent 100-Myr intervals as indicated by the scale bar.
