Comparison of the dR40 and dR40_Springer calibration bounds, joint marginal priors, and posterior divergence estimates for seven key clades. For each clade the calibration bounds and 95% CIs for marginal priors and posterior estimates are shown (above) for our preferred dR40 calibration set, and (below) for the dR40_Springer calibration set with calibration bounds substituted in from Springer et al. [10]. Posterior estimates are shown separately for the autocorrelated and independent rates models, however, the marginal priors under these two rates models are effectively the same, and here for clarity we average over the slight, primarily stochastic differences between them. (marginal priors and posterior estimates are provided in Additional file 2). Erinaceidae-Soricidae is further discussed in Additional file 1 (“Incorrect or poorly supported fossil placements”, 7)
