Additional file 3. Chronogram and table of inferred ages from the Bayesian random local clock molecular dating analysis of the seed-plant data set.
Figure. Bayesian random local clock dating of seed-plant phylogeny based on 13 plastid genes. Labelled nodes are cross-referenced with main text Table 1 and the Table below. The time scale is in Ma (geological time scale according the International Commission on Stratigraphy, 2012). Blue bars on nodes represent 95% HPD; red stars are minimum ages of calibration fossils (Table 1) and red bars are their assigned 95% prior age distributions. Numbers adjacent to branches are posterior probability support values (expressed as percentages). L, lower; Neog, Neogene; U, upper; T., Trithuria.
Table. Estimated ages of splits in seed-plant phylogeny based on a Bayesian random local clocks analysis of 13 plastid regions (see Figure above). Mean and 95% HPD are indicated for individual nodes labelled in the Figure above. All clades or taxa concern crown clades and taxa. MRCA, most recent common ancestor.
