The length of this giant shark, which became extinct about 3.5 million years ago, is estimated to be between 10 and 19 meters.

A group of scientists discovered fossil of a megadolon ancestor, a giant Shark lost historyA shark graveyard in the waters around Australia’s Cocos (Keeling) Islands in the Indian Ocean, scientific sources reported on Wednesday.

The discovery came during a research voyage on the Australian scientific agency CSIRO’s scientific vessel Investigator, exploring the ocean floor. that remote area is located in the middle Australia Y Sri Lanka.

on that mission, 750 mineralized fossils of shark teeth collectedof various modern and prehistoric predatory species, including the ancestors of the feared megadolon, which are believed to have measured between 10 and 19 metersAccording to a statement released today by CSIRO.

“This shark evolved into Megalodon, which It was the largest species of shark, although it went extinct about 3.5 million years ago.”explained Glenn Moore, Western Australian Museum curator of fish, who was involved in the CSIRO research.

Although considered as megadolon one of the most powerful predators in historyLittle evidence of its existence has been preserved, such as its teeth, so its appearance and the maximum size it reached are uncertain, the statement said.

CSIRO researchers believe – from the tooth they found – that This relative of the megadolon came to measure about twelve metres.

On scientific expedition on board the explorer, scientists too New species of sea creatures discovered todayMany of them are as yet unknown, such as the small striped horn shark, which is found off the coast of northwestern Australia.

“This species is unique to Australia, but has not yet been named or described. This species that we have collected will be of great scientific importance.” Noted Western Australian Museum curator of fish Will White.

This class of shark is also known as the horned shark (Heterodontus franchisi). animals that measure about a meter, move slowly And they are usually found in shallow water.

Just like that, These animals usually hide behind rocks or come out at night to search for algae and food on the sea floor, although the new species discovered in the CISRO expedition live in waters deeper than 150 metres, according to the statement.

“From the new little shark that lives on the ocean floor The giant ancient megasharks that once roamed the oceansThese biodiversity studies provide us with important information about life in our oceans,” said John Keesing, CISRO’s chief scientist.
