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]
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 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]
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 genus Cretalamna which lived from the mid-Cretaceous-Paleogene is believed to be directly ancestral to Otodus, and thus to megalodon. [5] There are certain dubious species of Otodontidae inclued species where teeth are not properly described, such as Otodus debrayi, Otodus stromeri, Otodus rondelettiformis, and Otodus hastalis. These ...

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]
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 ...
