The reason behind the mysterious disappearance of Megalodon, the largest shark that ever lived | Sciences

The struggle for food in prehistoric times may have meant the extinction of the megalodon shark, the largest shark that ever lived on the planet.

A study of the fossil teeth of this giant oceanic indicates that it needed to compete for food with another fierce predator, the great white shark. The battle to reduce the number of whales and other prey may have driven megalodon to extinction three million years ago.

But environmental pressures, such as sea level change, have also played a role.

The extinction of the megalodon is an ancient mystery. A number of different factors have been suggested, from habitat loss due to changing sea levels to declining prey numbers.

In the latest study, international researchers used zinc isotopes in the teeth of live and extinct sharks as a tool for understanding the nutrition of long-dead animals.

said Thomas Totkin, a professor at Johannes Gutenberg at Johannes Gutenberg University Mainz, Germany, who led the study.

Commenting on the research, which was published in Nature Communications, Catalina Pimento of Swansea University in Wales said more work is needed to solve the mystery of what happened to megalodon. According to her, extinction has been studied from many different angles over the past decade and studies point to several factors.

“It remains a mystery what megalodon ate and how well it competed with other sharks,” says Pimento.

How big was megalodon?

megalodon (Autodes Megalodon) a huge toothed shark that roamed the oceans from 3 to 22 million years ago. Its name means “big teeth”.

The white shark is three times the size of the great white, can reach 18 meters in length and weigh up to 60 tons.

Megalodon made news recently when a six-year-old boy stumbled upon the tooth of a shark belonging to a giant prehistoric megalodon in Suffolk, eastern England. Sammy Shelton found a 10 cm long tooth on Bawdsey Beach in Suffolk during a long vacation.
