The horror movie “great white shark” once left a terrible impression on the ocean, and even secretly felt lucky for the extinction of this legendary “megatoothed shark”. A team of researchers from the universities of Swansea and Bristol published their latest analysis of ancient sharks in the journal scientific reports on Thursday. < / P > < p > the study found that the dorsal fin length of the creature is more than 5 feet (1.6 meters), and the overall length is up to 52 feet (16 meters), which is longer than the buses in some cities. < / P > < p > in order to reconstruct the size of ancient megatoothed sharks that lived between 23 million and 3 million years ago, scientists have referred to a large number of fossil data. < / P > < p > in addition, lead author Jack Cooper and other team members extended the comparison to five modern shark species, 20 feet (6 meters) longer than the great white shark previously referred to. However, Catalina pimiento, co-author of the study and from Swansea University, added: “MEGALODON is not the direct ancestor of great white sharks, but is more directly related to other large predatory sharks.”. After understanding the growth curve of modern Shangyu, the researchers applied the model to the ancient giant tooth shark. The analysis of body size may help scientists understand how the species died out. Global Tech
