Description
Original diagnose after Fuchs et al. (2017) p. 250 [25903]: Carcharhiniform shark defined by small multicuspid teeth with a maximum width of about 500 mm and a strongly lingually inclined main cusp giving the teeth a relatively flat appearance. The crown consists of a main cusp and two to three pairs of lateral cusplets. The main cusp is triangular and possesses well-developed cutting edges, which are continuous between the main cusp and the lateral cusplets. In profile view, the lateral cusplets are more erected than the main cusp. On the labial crown face a prominent horizontal crest-like enameloid ridge occurs following more or less the outlines of the cusps. In occlusal view, the root is considerably U-shaped. Lingually, one central foramen below the main cusp and at least two pairs of margino-lingual foramina are developed. Labially, one central and one additional displaced foramen are developed.
