Horror in the Deep - Trailer (Tulip Entertainment)

The Megalodon shark was an ancient sea giant, a formidable monster shark of enormous size, considered the largest shark that ever lived (also the largest fish in Earth history), and unquestionably ruled the oceans about 23 to 3.6 million years ago - then extinct Mysteriously.

Now, scientists claim that the reason for their disappearance is the white gannet sharks, their nimble little rivals who fought with them over food and resources at sea.



The prehistoric shark lived over 3.6 million years ago and is known for its huge teeth and jaw, which allowed it to eat huge fish very easily.

The word glodon originates from Greek, where the words "megs" (you know the word "mega", big) and "udon" together mean "big teeth" or "big tooth".

Because the sharks have no bones, no bone fossils were left of it, but huge teeth were found, about 20 centimeters long each.

According to the tooth remains of this sea monster, it seems that this huge shark was about 20 meters long and even longer.

The weight estimate of this horrible monster was 13 times the weight of the giant white-faced shark of today, and 6 times the weight of the dinosaur T-rex.



Now, a new study conducted and examined the fossilized teeth of the Magellan, found that this shark was looking for the same food, or rather fish, like the white shark, all whales and dolphins.

Extinct by the white sharks?

In the study, published in the journal Nature Communications, the researchers examined zinc isotopes in the teeth of modern and fossil sharks from around the world, including the teeth of Magellan and white gourd.

This method allows scientists to study the level of nutrition (tropical level) of animals and thus understand their place in the food chain.

An analysis of the zinc levels found that the giant sharks were at the top of the food chain, meaning nothing ate them. There were indeed predators on primates - who are high up their food chain.

Professor Kenshaw Shimada, of DePaul University in Chicago, who was among the study's authors, said: "These results probably suggest that there was at least some overlap in the prey hunted by the two species of sharks."



How can it be that the disappearance of the greatest predator ever coincides with the rise of one of today's super predators?

One theory that aligns with the analysis in the latest study is that climate change is responsible.

During Maglodon's dominance, the climate was milder and the sea warmer, allowing the great predator to patrol all over the northern and southern hemispheres alike.

The rise of the great white sharks occurred in parallel with changing sea conditions and general cooling at both poles.

Cooler water means that krill have flowered in coastal areas, as have bolognese whales that feed on them.

Because the Magellan was able to survive only in warmer waters, the more adaptable ptarmigan sharks were able to take advantage of the absence of the main competitor and celebrate the growing whale populations.



White sharks seem to have enjoyed "the most capable survival," the Darwinian theory of evolution that attempts to describe the mechanism of natural selection.

People often confuse this Darwinian expression as meaning the strongest and greatest survivor.

But actually referring to which species is best adapted to survive the changes in the environment and emerge from the other side of life, when it is able to continue the lineage and reproduction of the species.

Or maybe he is not extinct?

Although according to all the experts' estimates these super sharks became extinct 3.6 million years ago, there are many on social media who are sure that they are still lurking in the depths of the ocean.

So for a while, a diver believes he found evidence of their return after spotting a passing shark while diving, with some bite marks on it.



Diver Jalil Najpov, 40, spotted the 4.5-foot-long shark swimming in front of Isla Guadeloupe in Mexico with bite marks on its side, sparking controversy as to their origin.

While some marine experts are trying to figure out why another shark bit its teeth aggressively at its species, others have theorized that it is not a bite from another large shark - but a much larger creature than a shark - the prehistoric monster from Glodon.

This claim is supported by other videos that have been released recently, which believers claim can be estimated that the huge creature is still alive.

Of course the allegations and concerns are provoking heated debates on the net, after images captured on Google Earth reveal suspicious sights.

Those who are convinced of its existence claim that most of the ocean creatures have not yet been exposed, and that there is an entire life at the bottom of the sea that a human eye has never seen.
