FIGURE 6. Melanosuchus latrubessei UFAC 2793 in details of the maxillary and premaxillary limits of the ventral portion in medial view. (A) Elucidating the preserved anterior limit of premaxilla; (B) The anterior limit of maxilla-maxilla suture and the posterior broken region of premaxilla; and (C) Zoom in the limit maxilla-maxilla suture elucidating an anterior smooth surface that is here inferred as the posterior limit for maxillary-vomer contact. Dark lines delimit the bone limits and sutures. Anatomical abbreviations: if, incisive foramen; EN, external nares; pmx, premaxilla; mx-mx, suture between maxillae; mx-v, suture between maxillary and vomer. Out of scale.
