Within the Otodus lineage; O. chubutensis is the succeeding species of O. angustidens and is followed by O. megalodon. [3] In short, O. chubutensis is considered a possible ancestor of O. megalodon. [3] [8] [9] However, due to its co-existence with O. megalodon during the Miocene and Pliocene epochs, it is regarded as a morpho-species. [3]
The genus Carcharocles may be invalid, and the shark may actually belong in the genus Otodus, making it Otodus megalodon. A 1974 study on Paleogene sharks by Henri Cappetta erected the subgenus Megaselachus, classifying the shark as Otodus (Megaselachus) megalodon, along with O. (M.) chubutensis. [5]
There is also potential evidence that Otodus hunted raptorial sperm whales; a tooth belonging to an undetermined 4 m (13 ft) long physeteroid closely resembling those of Acrophyseter discovered in the Nutrien Aurora Phosphate Mine in North Carolina suggests that a megalodon or O. chubutensis may have aimed for the head of the sperm whale in ...

The complete Otodus obliquus to C. megalodon transition then became clear and has since gained the acceptance of many other experts with the passage of time. Within the Carcharocles lineage, C. angustidens is the species succeeding C. sokolovi and is followed by C. chubutensis. [4]
A new study posits that the ancient megalodon shark was longer and slimmer than previously believed. The ancient shark has been compared to the great white, but it may have more closely resembled ...
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 ...
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]
