Surprising: They Find the Fossil of a Huge Prehistoric Shark Ancestor of Megalodon

SYDNEY, Australia – Scientists have discovered the fossil of an ancestor of Megadolon, a giant, historically extinct shark, in a shark cemetery in the waters around Australia’s Cocos, Keeling Islands in the Indian Ocean, sources said on Wednesday. Told.

The discovery was made during a research trip aboard the scientific vessel Investigator, belonging to the Australian scientific agency CSIRO, while searching the ocean floor of the remote area, located halfway between Australia and Sri Lanka.

On that expedition, 750 mineralized fossils of shark teeth were collected from various modern and prehistoric predatory species, including an ancestor of the feared megadolon, which is thought to have been 10 to 19 m (32 to 62 ft) long. were measured between A statement published by CSIRO.

“This shark evolved into megalodon, which was the largest species of shark, even though it went extinct about 3.5 million years ago,” explained Glenn Moore, Western Australian Museum curator of fishes, who was involved in research on the shark. CSIRO.

Although Megadolon is believed to be one of the most powerful predators in history, there is little evidence of its existence, 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 discovered – that this relative of Megadolon was once measured at around 12 meters (39 ft).

On scientific expeditions aboard the Explorer, scientists also discovered new species of modern marine animals, many of them hitherto unknown, such as a small striped horn shark found off the coast of northwestern Australia.

Western Australian Museum curator of fish Will White said, “This species is unique to Australia, but has yet to be named or described. The species we have collected will be of great scientific importance.”

Paleontologists claim to have discovered a species of marine animal that lived on Earth 130 million years ago. Guillermo Queiroz explains to us.

This class of sharks, also known as horned sharks (Heterodontus franchisi), are animals that measure about one meter, move slowly and are usually found in shallow water.

Furthermore, these animals usually hide behind rocks or seaweed on the ocean floor and come out at night in search of food, although the new species discovered by the CISRO expedition can live in water deeper than 150 m (492 ft). resides, according to the statement.

John Keesing, CISRO’s chief scientist, said: “From the tiny new sharks that live on the sea floor to the huge ancient megasharks that once roamed the seas, these biodiversity studies give us important information about life in our oceans.”
