FIGURE 18. Dental morphology of Aetosauroides scagliai (MCN-PV 2347, MCP-3450-PV and UFSM 11505). A, Transversal section of the premaxilla of MCN-PV 2347 showing the premaxillary tooth in mesial view. B-C, 3D reconstruction based on µCT-scan images of the premaxillary tooth in labial (B), distal (C), and basal (D) views. E, in situ maxillary tooth of UFSM 11505 in labial view. F, 3D reconstruction based on µCT-scan images of the maxillary tooth in basal view. G, medial view of maxilla and dentary of MCN-PV 2347. H, isolated dentary teeth of MCP-3450-PV. I-M, 3D reconstruction based on µCT-scan images of the dentary tooth of MCN-PV 2347 in basal (I), distal (J), labial (K), distal (L), and lingual (M) views. Abbreviations: cr, crown; es, enamel striation; i.ct, incipient constriction; itp, interdental plate; kn, knee; nt, new tooth; ro, root; rp, resorption pit.
