The divergence time estimates for internal nodes of the phylogeny of Strongylocentrotidae based on strict clock estimates calibrated to fossil record and previous studies. Labels for the internal nodes match those in Figure 4. A calibration of 5–12 Ma. at node C was used for ‘Fossil estimate’ and of 12–19 Ma. at node A was used for ‘12S rDNA rate estimate’.
