Description
Original diagnosis after Ginter, Hairapetian & Klug, 2002 [3140]: As for genus: Sharks with crushing teeth whose crowns are composed of a prominent, pyramidal central cusp and one to three pairs of lateral cusps. The size of the lateral cusps decreases mesially and distally, the basal parts (up to 2/3) of the cusps are fused together and the crown foot is convex which makes the crown resemble a fan or an oriental crown. Each cusp bears between one and four strong cristae at least on its lingual side. A row of additional small cusplets occurs just above the crown-base interface on the labial side. The base is extended lingually. The occlusallingual side of the base is perforated with numerous horizontal canals or grooves which continue into the crown and towards basal-labial openings; the basallingual part of the base is devoid of foramina. A narrow mesio-distal groove runs along the lingual crownbase interface.
