Genus Carcharias Rafinesque, 1810

The dentition is strongly heterodont, the teeth have typical odontaspid tooth morphology. All teeth have long, pointed main crown, bifurcated root with one or two pairs of cusplets. The cutting edges are smooth all along, they do not reach the base of the main crown. The anteriors are thin and slender, their main crown is elongated, symmetrical in labiolingual view, while strongly sigmoid in profile view. The lower laterals are similar to the anterior, but they are shorter, and less sigmoid. The distals and the upper laterals have a distally bent main crown.

The root has two, slender branches, with a massive central bulge on the lingual side. This bulge bears a visual nutritive groove. The cusplets of the anteriors are pointed and also slender, they are usually circular in cross-section. The laterals and distals have labiolingually straight, triangular cusplets. WEILER (1933, 1938) reported Carcharias acutissima (as Odontaspis acutissima ) from the Kiscell Clay, however, he did not figure these teeth, and he did not mention any detail about a possible ornamentation of the lingual face of the main crown, therefore this report could belong to any of the here detailed Carcharias morphogroups (see below).
