Maximum likelihood ancestral state reconstruction of marginal musculature form for the central region of the composite evolutionary tree (Fig. 3b) populated by Corralizoanthus, Savalia, Antipathozoanthus, and Parazoanthus taxa. Drawings to the right of tree represent extant forms of the isolated mesogleal structures supporting the marginal musculature. Pie chart sections represent the relative likelihood of each character state (that exceeded 5 %) at the node and are enlarged at ancestral nodes to increase clarity
