Summary of evidence for a macroevolutionary model of edentulism in vertebrates. (A) Evidence from extant nonavian vertebrate lineages with complete or near edentulism, showing phylogenetic and trophic diversity of ontogenetic tooth loss. (B) Evidence from select theropod dinosaur lineages focusing on Coelurosauria and showing independent evolution of adult edentulism at least seven times (1–7). ?, hypothesized state/partial evidence; B, baleen; Bb, barbels; DR, sexually dimorphic reduction pattern; E, electroreception; F, filtration; G, gastric mill/gizzard; H, expanded hypapophyses; R, rhamphotheca; S, suction feeding; Sw, sword; T, projectile tongue.
