FIGURE 39. Tip-dated allcompat tree from posterior sample of Bayesian analysis (with full dataset). Branch colours show evolutionary character state transition rates (in character transitions per million year). Nodes below 50% posterior probability are collapsed into polytomies for which evolutionary rates cannot be calculated.
