The difficult reason makes the Megalodon shark extinct

The world's largest creatures - including whales and sharks . are hiding in the deep sea. Even when dinosaurs still dominate the ground, the undersea has creatures of exceptional size. Among them is Megalodon - the super shark of three times the size of the white shark today.

Megalodon and T-rex.

Super Megalodon shark appeared from 23 million years ago, with a length that can grow beyond 20m, with a powerful bite without any creature in history compared. Based on data from computer models, scientists believe that the bite force of Megalodon can be up to 11-18 tons, enough to crush a car.

This also means that no creature in the ocean ever has the power to rival Megalodon. But if they are, why are they extinct?

Megalodon's unrivaled chatter.

This question has been troubling scientists for many years, and fortunately we have recently found the answer. Specifically, after analyzing a sample of fossil teeth, experts believe that they are extinct because of too . picky, picky.

Experts from the University of Pisa (Italy) analyzed a number of traces and wounds on a fossilized tooth from 7 million years ago to find Megalodon's diet . This tooth sample is found at Aguada de Lomas (Peru).

Fossil teeth from 7 million years ago are the key to research.

Accordingly, the analysis shows that Megalodon's main prey is a dwarf whale , called Piscobalaena nana , and an ancestor of a seal - the Piscophoca pacifica.

Global climate change around 2.6 million years ago has made the number of dwarf whales plummet. At that time, the global temperature dropped, leading to a decline in seawater, frost formed at the two poles. All pushed the dwarf whales to the expansive seas - the environment didn't suit them.

Meanwhile, Megalodon only eats dwarf whales and cannot switch to other prey. After all, ancient monsters were unable to adapt and fall into extinction.

"The super megalodon shark is extinct due to the decline of a number of small horned whales - a great relative of the giant horned whale," - Alberto Collareta research leader from Pisa University (Italy) said. .

Livyatan Melvillei - carnivorous whales are believed to compete with Megalodon.

Research has set a new hypothesis about how ancient "invincible" super sharks disappeared. However, there is an opinion that Megalodon is also influenced by another "monster" fish, Livyatan Melvillei - the thriving predatory whale of the time Megalodon regresses.
