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 evolution.
Carcharodon (meaning "jagged/sharp tooth" in Ancient Greek) [2] is a genus of sharks within the family Lamnidae, colloquially called the "white sharks." The only extant member is the great white shark ( Carcharodon carcharias ).
Carcharodon megalodon indica Otodus chubutensis , [ 1 ] meaning "ear-shaped tooth of Chubut ", from Ancient Greek ὠτ (ōt, meaning "ear") and ὀδούς (odoús, meaning "tooth") – thus, "ear-shaped tooth", is an extinct species of prehistoric megatoothed sharks in the genus Otodus , that lived during Oligocene , Miocene , and Pliocene ...
Like contemporaneous sharks, at least two species of Otodus (O. angustidens and O. megalodon) made use of nursery areas to birth their young in, specifically warm-water coastal environments with large amounts of food and protection from predators. [14] [10] A possible reproduction area of O. obliquus has been discovered in the Ganntour basin ...
The Swiss naturalist Louis Agassiz, first identified this shark as a species of genus Carcharodon in 1835.. In 1964, shark expert, L. S. Glikman recognized the transition of Otodus obliquus to C. auriculatus and moved C. angustidens to genus Otodus.
The taxonomic assignment of C. megalodon has been debated for nearly a century, and is still under dispute. The two major interpretations are Carcharodon megalodon (under family Lamnidae) or Carcharocles megalodon (under the family Otodontidae). Consequently, the scientific name of this species is commonly abbreviated C. megalodon in the ...

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.
