FIGURE 17. 3D in Skull osteology of Aetosauroides scagliai Casamiquela, 1960 (Archosauria: Aetosauria) from the Late Triassic of Brazil: New insights into the paleobiology of aetosaurs

FIGURE 17. 3D Reconstruction based on µCT-scan images of the right angular (A–E), prearticular (F–H), and surangular (I–K) of Aetosauroides scagliai (MCN-PV 2347) in lateral (A, H, and I), antero-medial (B and J), medial (D, G, and K), dorsal (F), posterior (C), and ventral (E) views. Abbreviations: aang, articulation surface with the angular; asar, articulation surface of the articular; asp, articulation with the splenial; asu, articulation with the surangular; e, elevation; mf, mandibular fenestra; mk, internal meckelian groove; rap, retroarticular process; sufe, surangular foramen medial exit; sufo, surangular foramen; sup, surangular process; sus, medial shelf of the surangular; tu, surangular process; vs, ventral shelf of the angular.
