Description
Original diagnose after Guinot et al. (2014) p. 78 [20107]: Scyliorhinid teeth showing a moderate degree of gradient monognathic heterodonty. Teeth small (not exceeding 1.5mmwide) with erect and sharp main cusp. Presence of a pair of lateral cusplets in anterior files, two in more laterals. Cusplets rather low, broad and well separated from main cusp and implanted high on the crown. Basal labial crown edge slightly concave and not overhanging the root by a bulge. About 15 vertical labial folds showing a basal thickening are present on the labial crown face. Folds can reach the apexof the cusplets and can reach the three-quarters or the main cusp near the cutting edges (higher in posterior teeth). Lingual crown face transversely convex with slight vertical folds on main cusp and cusplets not reaching the crown/root edge. Broad and flat basal root face with moderately flared edges. Nutritive groove partially open labially. Broad lingual protuberance and rounded root lobe extremities. Narrow and Omega-shaped median root notch. Lateral teeth with distally inclined crown and more labio-lingually compressed.
