J. Kriwet et al. 2008Lamniform sharks only known by isolated teeth and characterized by the following combination of characters: tearing-type dentition with very weak gradient monognathic heterodonty; a single pair of parasymphyseals(?) present; mesiodistally compressed teeth, with generally a single pair of lateral cusplets; robust roots with short branches; lingual protuberance more or less massive; with nutritive groove, which might be secondarily closed.
