FIGURE 16. 3D Reconstruction based on µCT-scan images of the posterior portion of the mandible of Aetosauroides scagliai (MCN-PV 2347). A, articulation between the left quadrate and left mandible in postero-lateral view (including the position of the stapes). B, left articular in posterior view. C, left articular in dorsal view. D, left mandible in posterior view. E, left articular in lateroventral view. F, left articular in ventral view; G, left mandible in lateral view. H, left mandible in medial view. I, left mandible in dorsal view. J, left surangular in medial view. Abbreviations: ar, articular; as, glenoid; asar, articulation facet for the articular; b.su, broken surface of the surangular; e, elevation; fo, foramen; lw, lateral wing of the quadrate; par, prearticular; parc, prearticular contact of the articular; qc, quadrate crest; qfo, quadrate foramen; qh, quadrate head; rap, retroarticular process; st, stapes; su, surangular; suas, surangular articulation with quadrate; suc, surangular contact of the articular; sufe, surangular foramen medial exit; sufo, surangular foramen; sus, medial shelf of the surangular; vr, ventral ridge.
