Results obtained under the FBD and SFBD tree models with no sampling of ancestors (NoSA_Diversity) taxon sampling strategy and distinct relaxed clock models. Median values are reported given the very broad and skewed 95% HPD distributions. Abbreviations: M median value for node age, Rng HPD range between lower and upper bound values for the 95% HPD, S sampling strategy
