Nodes in bold were employed as calibrations in the divergence time analyses. The mean node age and lower and upper bounds of the 95% HPD are shown for each node. Summary statistics provided include the absolute and percentage difference in mean node age (Dmean and%Dmean, respectively), and the absolute and percentage difference in the width of the 95% HPD Node Age (DHPD and%DHPD, respectively).
