Ancestral character state reconstruction of terapontid intestinal morphology. Summary of maximum likelihood (left graph) and maximum parsimony (right) ancestral character reconstruction of adult intestinal configuration for 450 terapontid trees displayed on the maximum clade credibility tree. Circles at terminal nodes represent the observed character state for extant species. Pie charts for ancestral nodes show estimated proportions for reconstructed character states at that internal node.
