Additional file 5: of Fossils matter: improved estimates of divergence times in Pinus reveal older diversification

Comparison of estimated node ages of the 19 major clades of Pinus across all applied dating approaches. Boxplots illustrate the estimated node ages across dating approaches and fossil sets for the major clades (a-s illustrated in Fig. 2 ). Whiskers span the 95% highest probability density (HPD), while boxes span the 50% HPD, with the median node age indicated by a vertical bar. The x-axis indicates the geological time in million years. The following abbreviations are used. FBD: fossilized birth-death method using “tip date” approach. FBD age range using “age range” approach. ND: node dating method; l: analyses based on the large fossil set; s: analyses based on the small fossil set; n: narrow log normal calibration priors in ND based on the geological age of the respective fossil; b: broad log normal calibration priors in ND; u: uniform calibration priors. The lower and upper limits of the uniform distribution represent the 2.5% and 97.5% CI levels used for the log-normal priors in the NDb method. (PDF 68 kb
