  1. Node numbers correspond to Figure 1. Dates and 95% confidence intervals are in millions of years ago, with the latter applying to the input dates only. Fossil dates correspond to those listed in Table 5 and act as constraints on the minimum divergence time for the node in question. The date for node 35 was interpolated according to a constant birth model (see Methods). Support values for each node, as measured by rQS [51, 52] are also provided.
