Table 3.
Summary of key parameters for the three main analyses. Note: the tMRCA is the time of the most recent common ancestor of all taxa, including both extinct and extant species. The 95% HPD interval for each estimate is in square brackets. The morphological clock rate is given in per cent change per million years.
