Evolution of anterior and posterior mechanical advantage of the jaw adductor muscles in Ankylosauria. Anterior (a) and posterior (b) mechanical advantage mapped onto a time-calibrated phylogeny of Thyreophora. (c) Phylomorphospace of anterior and posterior mechanical advantage. Silhouettes from PhyloPic (phylopic.org) and original sources.
