  1. The two-rate analysis with all fossil calibrations (in bold) is the overall best supported analysis, based on the Bayes Factor analyses (see below). The best supported analysis for each clock rate model is denoted by a a. Numbers outside of brackets are median divergence times and numbers in brackets indicate the 95% highest posterior density (HPD) intervals
