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]
Megalodon. Otodus megalodon (/ ˈmɛɡələdɒn / 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.
The fact that the bite marks were found on the tooth's roots further suggest that the shark broke the whale's jaw during the bite, suggesting the bite was extremely powerful. The fossil is also notable as it stands as the first known instance of an antagonistic interaction between a sperm whale and an otodontid shark recorded in the fossil record.
A shark-like image on their fish finder conjured images of a giant shark that swam the oceans millions of years ago. Shark-like underwater image conjures thoughts of 50-foot, 40-ton Megalodon for ...
However, in 1987, shark expert H. Cappetta recognized the C. auriculatus - C. megalodon lineage and placed all related megatooth sharks along with this species in the genus Carcharocles. 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.
Megalodon sharks were “the size and weight of a railroad car” and reigned over the world’s oceans “roughly 23 to 3.6 million years ago,” according to the National Museum of Natural History.
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] Recent studies of the newly described genus Megalolamna indicate that the ...
