FIGURE 23 in Skull osteology of Aetosauroides scagliai Casamiquela, 1960 (Archosauria: Aetosauria) from the Late Triassic of Brazil: New insights into the paleobiology of aetosaurs

FIGURE 23. Morphological features related to feeding strategies in Aetosauria in a phylogenetic perspective. A, simplified genus level phylogeny of Reyes et al. (2020). We coalesced the clade formed by Calyptosuchus, Adamanasuchus and Scutarx (C. complex) as no dental information is available for these taxa and they all share the same overall body-shape. B, ziphodont teeth. C, folidont teeth with marked serrations. D, folidont tooth with tooth wear. E, elongated folidont teeth with tooth wear. F, folidont to bulbous teeth with grooves/flutes. G, bulbous teeth with enamel striations. H, shovel-shaped premaxilla. I, medial dorsal process of the articular; J, glenoid placed ventral to the tooth line in the mandible. K, glenoid placed near or dorsal to the teeth line in the mandible. L, wide-body morphology indicating large gastric cavities. Dark circles indicate presence, white circles indicate absence and gray circles indicate missing data. Silhouettes at the right side show the overall body shape of aetosaurs as suggested by Desojo et al. (2013), in red the 'narrow-body', in orange the 'wide-body' and in blue the 'spinose'. Abbreviations: A, Aetosaurinae; D, Desmatosuchini; S, Stagonolepididae; St, Stagonolepidoidea; T, Typothoracinae.
