Carcharocles is a dubious genus of extinct sharks, belonging to the order Lamniformes and is part of the shark family Otodontidae.[1] They lived from the Late Eocene to the Late Pliocene. The genus is said to have descended from another otodontid shark genus called Otodus.[2] The genus usually includes the species informally known as megalodon (i.e., Carcharocles megalodon); however, some taxonomic authorities place that species in various other genera.[3] Some authors consider the genus Carcharocles a subgenus of Otodus,[4] including a study of Megalolamna's taxonomic relationships that demonstrates the possibility that Otodus needs to include the species sometimes assigned to Carcharocles (i.e., the megatoothed lineage, including megalodon) in order to be monophyletic.[3]

Species

Carcharocles aksuaticus? Early Eocene, 56–47.8 (Menner, 1928)
Carcharocles sokolovi? Late Eocene to Early Oligocene, 35 to 30 Ma Jaekel, 1895
Carcharocles auriculatus? (type), Late Eocene to Late Oligocene, 35 to 25 Ma (Blainville, 1818)
Carcharocles angustidens?, Early Oligocene to Early Miocene, 33 to 22 Ma (Agassiz, 1843)
Carcharocles chubutensis?, Oligocene to Pliocene, 28 to 5 Ma (Ameghino, 1901)
Megalodon (Carcharocles megalodon)?, Early Miocene to Late Pliocene, 23 to 3.6 Ma (Agassiz, 1843) (genus disputed)
