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 ...

Archaeolamna (from Greek arche which turned into archaeo and Lamna, an extinct shark genus) [1] is an extinct genus of mackerel sharks that lived during the Cretaceous.It contains three valid species (one with two subspecies) which have been found in Europe, North America, and Australia.
The fossils of Otodus sharks indicate that they were very large macro-predatory sharks. [7] The largest known teeth of O. obliquus measure about 104 millimetres (4.1 in) in height. [8] The vertebral centrum of this species are over 12.7 cm (5 inch) wide. [7] Scientists suggest that O. obliquus would have measured about 8–9 metres (26–30 ft ...
