FIGURE 21. Comparisons of maxillae, jugals, and quadratojugals of Aetosauria and non-aetosaur pseudosuchians. A, the non-stagonolepidide aetosaur Aetosauroides. B, Revueltosaurus (redrawn from Nesbitt, 2011). C, the erpetosuchid Tarjadia (redrawn from Ezcurra et al., 2018). D, the aetosaur Desmatosuchus (redrawn from Small, 2002). E, the aetosaur Stagonolepis robertsoni (redrawn from Sulej, 2010). F, the aetosaur Neoaetosauroides (redrawn from Desojo and Báez, 2007). G, the aetosaur Stenomyti huangae (redrawn from Small and Martz, 2013). H, the aetosaur Paratypothorax andressorum (redrawn from Schoch and Desojo, 2016 with modifications, see text). I, the aetosaur Aetosaurus ferratus (redrawn from Schoch, 2007 with modifications, see text). J, the basal phytosaur Diandongosuchus (redrawn from Stocker et al., 2017). K, the loricatan Postosuchus (redrawn from Nesbitt, 2011). L, the loricatan Prestosuchus (based on UFRGS-PV-0152-T and Mastrantonio et al., 2019). M, the ornithosuchid Riojasuchus (redrawn from Bakzco et al., 2018). N, the gracilisuchid Gracilisuchus stipanicicorum (redrawn from Nesbitt, 2011 and observations of Butler et al., 2014). O, the crocodylomorph Dromicosuchus (redrawn from Nesbitt, 2011). Colors indicate bone elements: orange, maxilla; blue, jugal; purple, quadratojugal. Not to scale.
