FIGURE 9. Bayesian inference phylogeny for extant chelydrids (Chelydra and Macrochelys). Note that representative skeletal synapomorphies in skull and carapace (above and below, respectively, next to lineage name) are provided for each lineage of Macrochelys; values above major nodes represent posterior probabilities (≥ 95%); values below major nodes represent the mean divergence time estimation of the most recent common ancestor (MRCA); and bars at major nodes represent 95% Highest Posterior Density (HPD).
