Like other known megatooth sharks, the fossils of O. angustidens indicate that it was considerably larger than the extant great white shark, with the largest individuals possibly measuring up to 11–12 metres (36–39 ft) long. [7] [8] A well preserved specimen from New Zealand is estimated at 9.3 m (31 ft) in length. [5]
The shark's vertebrae may have gotten much bigger, and scrutiny of the specimen revealed that it had a higher vertebral count than specimens of any known shark, possibly over 200 centra; only the great white approached it. [35]
In 1987, shark researcher, H. Cappetta reorganized the O. auriculatus - O. megalodon lineage and placed all related megatoothed sharks along with this species in the genus Carcharocles ( now Otodus). [7] Finally, the complete Otodus obliquus to O. megalodon progression became clear and has since gained the acceptance of many shark researchers. [8]

The original hypothesis of the great white shark's origin held that it is a descendant of a lineage of mega-toothed sharks, and is closely related to the prehistoric megalodon. [29] [30] These sharks were considerably larger in size, with megalodon attaining an estimated length of up to 14.2–20.3 m (47–67 ft).
The largest shark in the fossil record is the megalodon (Otodus megalodon), a colossal Neogene lamniform. The range of estimates of the maximum length for megalodon are from 17 to 20.3 m (56 to 67 ft), with a mass ranging from 65 to 114 short tons (59 to 103 t). [44] [45] [46] It is also regarded as the largest macro-predatory fish ever.
