Finally, the complete Otodus obliquus to O. megalodon progression became clear and has since gained the acceptance of many shark researchers. [8] 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.
Otodus megalodon (/ ˈ m ɛ ɡ əl ə d ɒ n / MEG-əl-ə-don; meaning "big tooth"), commonly known as megalodon, is an extinct species of giant mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Early Pliocene epochs.
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). [41] [42] [43] It is also regarded as the largest macro-predatory fish ever.
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 ...
“We waited for one of the rods to go off.”
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 ...
A new study finds that megatooth sharks’ warm-blood adaptation and giant size may have played a role in their extinction.
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 ...
