Original diagnose after Marramà et al. (2020) p. 1523 [28661]: Platyrhinid characterized by the following combination of characters: rostral cartilage very long, 1522 G. Marram a et al. almost reaching the anterior border of the disc; anterior fontanel extending through the entire length of the rostral cartilage with a closed and concave posterior border; nasal capsules at right angles to the rostrum; single small horn on nasal capsule; large space between the hyomandibulae and mandibular arch; approximately 132 vertebral centra (20–24 trunk centra; 113–118 centra from puboischiadic bar to the tip of tail); 15 or 16 rib pairs; 81–87 pectoral radials (35–38 propterygial, 8–10 mesopterygial, 38–41 metapterygial); 18–21 pelvic radials; short, straight and stout claspers (about 10% of total length; TL, hereafter); 20–25 caudal-fin radials on both ventral and dorsal sides (40–50 in total); thorns absent.
