Supplementary Figure 8: Detailed comparison of methods and datasets. For calibration #1, the age estimates (in million years ago) are represented for nodes that were shared between phylogenetic trees of plastid and nuclear markers. The ages are represented independently when produced by BEAST and MULTIDIVTIME. Black circles are ages based on the whole plastid dataset, red squares are ages based on plastid markers for 28 species only, black triangles are aged based on the whole nuclear dataset, and red bars indicate the interval between the 1st and 3rd quartiles of 100 replicates of the nuclear dataset decreased to the size of the plastid dataset. Taxonomic groups are indicated on the bottom. The last point corresponds to the crown of BEP, and the horizontal bar indicates the minimal age for the clade that would be congruent with the 67 Ma phytolith fossil (Prasad et al. 2011). Numbers can be used to identify the corresponding nodes in Supplementary Figure 9.
