Description
Original diagnosis after Adnet, Mouana, Charruault, Essid, Ammar, Marzougui, Merzeraud, Tabuce, Vianey-Liaud & Marivaux, 2018 [26014]: Fossil species of Pastinachus only known by abundant isolated teeth displaying a large size (up to 6.7 mm wide) and particularly thick and robust crowns with presence of a salient bulge on labial face (under the labial visor) in lateral teeth. When unworn and unaltered, the occlusal surface of crown of antero-lateral teeth shows a fine and irregularly pitted or alveolate ornamentation of its enameloid. Rhombic to hexagonal in shape, the crown is extremely elongated in the lateral upper teeth (twice broader than long), a peculiar shape reminiscent to that observed in upper teeth of myliobatids and rhinopterids.
