Comparison of date estimates of key nodes in passerine phylogeny across three fossil calibration schemes (sets A–C; a detailed description is provided in Materials and Methods) using log-normally distributed priors. Bars represent 95% credible intervals of joint priors [Markov chain Monte Carlo (MCMC) without data] and posteriors of random samples of 25 loci. Color boxes in the heading for each node indicate the set(s) of calibrations in which the node was used as a calibration point. Date estimates from previous studies (3–5, 19) for the same node are also shown, if available.
