  1. Dates refer to the crown ages of placental mammals and ten of the twelve interordinal clades identified by Meredith et al. [2] among the primary placental diversification spike. The two other clades, Afroinsectiphilia and Zooamata are excluded in the 122 taxon data sets based on Springer et al.’s [10] deletion of large, long-lived taxa. The average of independent (ind) and autocorrelated (auto) rates model divergence dates are provided for A-D, with 95% credible intervals provided for the dR40 timetrees for both the independent rates (E) and autocorrelated rates (F) analyses. (A) divergences from Phillips ([11], Fig. 4d), (B) Springer et al.’s [10] 122-taxon reanalysis of Phillips [11] with a new calibration scheme, (C) our analysis of the 122-taxon data set focusing on Phillips’ [11] calibrations, and then adding eight further calibrations (D-F, see Additional file 3)
  2. aIn Springer et al. [10] Scandentia groups with Glires, hence, we show the age of that grouping instead of Archonta (Scandentia/Primatomorphia)
