Megalodon is considered to be a member of the family Otodontidae, genus Otodus, as opposed to its previous classification into Lamnidae, genus Carcharodon. [ 21 ] [ 24 ] [ 22 ] [ 7 ] [ 25 ] Megalodon's classification into Carcharodon was due to dental similarity with the great white shark, but most authors believe that this is due to convergent ...
Otodus includes species that have not yet been formally described. One of these is Otodus debrayi, which is known to have lived in the Early Eocene and Middle Eocene epochs. This species has been found in Africa, North America, Central Asia, and Europe, dating from 47.8 to 38 milion years ago.
Otodontidae is an extinct family of sharks belonging to the order Lamniformes.Its members have been described as megatoothed sharks. [1] [2] They lived from the Early Cretaceous to the Pliocene, and included genera such as Otodus, including the giant megalodon. [3]
Members of the group include macropredators, generally of medium-large size, including the largest macropredatory shark ever, the extinct Otodus megalodon, as well as large planktivores. [ 2 ] Although some authors have argued that the Late Jurassic Palaeocarcharias should be considered the oldest known lamniform, this is disputed.
The fossil "mega-toothed" sharks like megalodon have also traditionally been placed in Carcharodon, [5] but most current literature refutes this position, placing mega-toothed sharks in a separate family, Otodontidae, and genus, Otodus (Carcharocles). [3] [13] Carcharodon caifassii is the other species in genus Carcharodon. It is a debated ...

Otodus megalodon teeth are the largest of any shark, extinct or living, and are among the most sought after types of shark teeth in the world. This shark lived during the late Oligocene epoch and Neogene period, about 28 to 1.5 million years ago, and ranged to a maximum length of 60 ft. [ 13 ] The smallest teeth are only 1.2 cm (0.5 in) in ...
With these remains, the study authors determined that Ptychodus belonged to the order of sharks known as Lamniformes, or mackerel sharks, the same group that the extinct Otodus megalodon and the ...
