FIGURE 7. The vomer anatomy of Melanosuchus niger specimens (UFAC R-136 and UFAC R-203) in comparison with Paleosuchus palpebrosus specimen (UFAC R-215). (A) Anterodorsal view of the inside of external nares, in red, the articulated vomer in Melanosuchus niger (UFAC R-136); (B) Schematic draw of figure A; (C) Medial view of right rostrum of Melanosuchus niger (UFAC R-203) highlighting the contacts of vomer with premaxilla and maxilla after the bone removal; and (D) Paleosuchus palpebrosus specimen (UFAC R-215) illustrating an example where the vomer is fused with other bones. Dark lines mark bone limits and sutures. Anatomical abbreviations: if, incisive foramen; EN, external nares; pmx-mx, suture between premaxillary and maxillary; pmx-v, suture between premaxilla and vomer; pmx, premaxilla; mx-mx, suture between maxillae; mx-v, suture between maxillary and vomer; mx, maxilla; n, nasal; v, vomer.
