The limits of convergence: the roles of phylogeny and dietary ecology in shaping non-avian amniote skulls

Keegan Melstrom, Kenneth Angielczyk, Kathleen Ritterbush & Randall Irmis
Cranial morphology is remarkably varied in living amniotes, ranging from short-faced mammals to the elongate snouts of crocodylians. This diversity of shapes is thought to correspond with feeding ecology, a relationship repeatedly demonstrated at smaller phylogenetic scales, but one that remains untested across amniote phylogeny. Using a combination of 2D geometric and linear morphometrics, we investigate the links between phylogenetic relationships, diet, and skull shape in an expansive dataset of extant amniotes with teeth: mammals,...
