The dentition of C. mantelli is among the best-known of all extinct sharks, thanks to fossil skeletons like FHSM VP-2187, which consists of a near-complete articulated dentition. Other C. mantelli skeletons, such as KUVP-247 and KUVP-69102, also include partial jaws with some teeth in their natural positions, some of which were not present in ...
