Description
Original diagnose after Pollerspöck & Straube (2017) p. 35 [25359]: Teeth 0.5–0.7 mm high, multicuspid with a single to two pairs of lateral cusplets. The first pair of cusplets may reach two thirds of the height of the main cusp. The lingual sides of the main and lateral cusps are convex, less distinct from the labial side. No labial/lingual compression of the crown/root. As with many other scyliorhinid shark teeth, there is a reticulate ornamentation reminiscent of the surface of a golf ball on the labial side of the teeth. The cutting edges cover the entire occlusal edge in all cusps. The root shows two lobes with two central foramina. The lingual protuberance of the root is only weakly developed; there is no nutritive groove between the two root lobes. The root is holaulacorhizid and the type of dentition is likely of the clutching-type (Cappetta 2012).
