Table 1 Ages for the main cycad clades retrieved in our analysis and compared with ages reported from the node-calibration analysis of Condamine et al. (2015).

Ages (Ma) from
For the latter study, only ages from the analysis with the full fossil dataset and the birth-death tree prior are reported. Min and max ages represent the upper and lower boundary of the 95% Highest Posterior Density. Ma, million years ago.
