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]
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]
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 ...

Wanner concluded that the teeth were of a closely related new species and placed it under the taxon Otodus biauriculatus. [16] In 1935, French Paleontologist Camille Arambourg described a new subspecies of C. biauriculata from teeth found in Moroccan phosphates under the taxon Lamna biauriculata maroccana , [ 17 ] which was elevated into its ...
Otodus angustidens [3] is an extinct species of prehistoric megatoothed sharks in the genus Otodus, which lived during the Late Eocene and Miocene epochs about 34 to 21 million years ago. [4] The largest individuals were about 11–12 metres (36–39 ft) long. This shark is related to another extinct megatoothed shark, the famous Otodus ...
