Figure 3. — Pantherine fossil record and fossil calibration points. (a) Stratigraphic ranges of previously known fossil record of Pantherinae (Panthera + Neofelis), compared with the age of P. blytheae and previous divergence time estimates based on molecular data and nodal calibration points. Geologic age data taken from [4,5,8,9,13–16]. (b) Divergence time estimates for extant Panthera based on node dating using Bayesian relaxed-clock analysis of nDNA sequences. Estimates from Johnson et al. [1]. (c) Estimates using 3.8 Ma as the minimum age of Panthera. (d) Estimates using 5.95 Ma, lower age limit of P. blytheae, as the minimum age of Panthera. Shaded bars indicate 95% HPD, node values are means. Dark bar on the timescale indicates the stratigraphic range of P. blytheae. (Online version in colour.)
