The bite of the ancient shark is even more powerful than the T. rex dinosaur

The most powerful bite of all time is the possession of the prehistoric giant shark Megalodon. Its biting makes T. T. Rex dreadful.

The giant Megalodon shark (meaning ' Greek Large' 'Large Tooth ) can span up to 50 fit and weigh up to 110 tons, at least 30 times heavier than its largest relative present today - giant white shark.

The fossil shows that Megalodon 'hunts prey alive and kills a large whale by grabbing the tail as well', according to researcher Stephen Wroe and New University paleontologist South Wales in Sydney, Australia.

Researchers have applied sophisticated computing techniques to analyze the bite of giant white shark and megalodon shark thanks to a software program that engineers use to reproduce 'everything from species. snail snail to the bridge or spacecraft '.

The 3D digital model he and his colleagues developed, based on the X-ray image of an 8-foot male white shark, recreated the shark's skull, jaw and muscles from nearly 2 million feet. tiny parts that link together. Wroe said: 'It takes a lot of computing power to be able to analyze something that is relatively simple like the jaw because you're dealing with all the complex shapes in biology'.

Scientists have had a lot of effort in the past to be able to find out how powerful the white shark's bite is. It seems that people are underestimating the power of white sharks because they only play prey in front of the enemy.'If it is a relatively small goal, and if they are not sure what the goal is, they can bite off the pair - whether bone or steel. Then you probably won't have a chance to witness the extreme power of this shocking bite. '

The largest white sharks have bite force of up to 2 tons, 3 times larger than the bite of African lions and 20 times the bite of humans. 'This is the largest bite force known in the world of mammals that exist today, even though killer whales or crocodiles may have stronger bite forces.'

Although white sharks have such tremendous power, its extinct giants even go far beyond the race with 10 times the bite force making them the most feared predators. once existed on Earth. Compared to Tyrannosaurus rex, this 'tyrant lizard' is no match for the extinct Megalodon shark. Tyrannosaurus has a bite force of about 3.1 tons, 'larger than the existing white shark but a modest number for the' Big Teeth '.

Wroe added: 'I must say I'm quite impressed with the complex and sophisticated digestive apparatus of sharks. With all the mammalian predators I observed, a lot of muscle force for the bite was lost. But sharks possess a more efficient leverage system. '

The frightening power these hunters use has shown their style. 'They follow big prey that can hurt them, and they don't want to. So they attacked with a heavy injury and then turned back to wait for the dead prey to die from blood loss , "Wroe explained. Other creatures may also hunt with the same method, including lizards and allosaur-like dinosaurs.

Sharks of sharks are probably particularly scary even though they have no bones, their body frames are made up of cartilage - the type of tissue that makes up human ears.

'Although cartilage is more flexible than bone but sun does not reduce the bite much, perhaps only about 5% or less'

. The high flexibility of the body frame can explain why sharks have such an effective bite.

But the bite of the shark is not so special. 'In a weight unit, most dogs and cats have an even stronger bite. But because sharks are so big, there's such a terrible bite. '

Despite the powerful bite of the shark, the ability to damage prey is largely dependent on the sophisticated design of the intimidating jaw . Wroe explained: 'Their teeth are very sharp, serrated like beef knives, so they don't need to use so much force to bite or tear fresh meat. They have tooth conveyors, so teeth continue to grow in rows. The shark tooth falls off and is replaced before it can wear away. '

Admittedly, 'estimating the bite force of a dead big fish must have been a secret' . But the method that Wroe and his colleagues used to analyze the jaws of sharks can help find better ways to reconstruct the face of a human after a shock. 'The way we reproduce shark's jaws is exactly the way we model human faces'.

Wroe's research may also help design more effective shark protection devices. 'Realistic big sharks often cause significant damage to underwater communication systems'.

Scientists are now studying many extinct creatures and existing species, including giant sea reptiles, giant carnivorous, extinct, like Australopithecus africanus (relatives). close to modern people) and Paranthropus, has long been known to anthropologists as Nutcracker Man with great jaws. 'We can get amazing information about the ecology as well as the evolution of an animal by understanding how it eats. This is a very important activity of animals'.

Wroe and colleagues will publish details of their study in the upcoming issue of the Journal of Zoology.
