In ancient times, there was an extremely terrible creature on the earth. It was Megalodon, a carnivore with a length of 2 meters and a weight of 1 tons, which could swallow dozens of people in one gulp.

According to the analysis of fossil sampling, it has more than 25 teeth as sharp as a boulder, and the length of each tooth is more than 2 cm, which can easily tear the prey apart. Some researchers speculate that the bite force of Megalodon can even reach 3 tons, which is three times higher than that of Tyrannosaurus Rex, and it is the most powerful earth creature known to human beings at present.

Because of his huge size, he consumes more than two tons of food every day, and many mammals are his delicacies. Before he preys, he will gradually approach his prey from below, attack its fins and tail, make it completely lose its ability to escape, and finally enjoy it. However, such a creature that once dominated the ocean suddenly disappeared from the earth 2.6 million years ago, leaving almost no fossil remains, which once puzzled many scientists.

in 1843, biologists found that the body of Megalodon shark was mostly composed of cartilage, and cartilage fossils were extremely difficult to preserve, which made it difficult for humans to find its complete skeleton. At present, we can only infer the extinction cause of Megalodon from the tooth fossils. According to the mainstream view, the extinction of Megalodon may be caused by the radiation generated by the supernova explosion at that time, because scientists found a rare isotope iron -6 in the chemical composition of its teeth, which does not exist on the earth at all and will only be produced when a supernova explosion occurs.

At the same time of Megalodon's disappearance, people found that other creatures on the earth were also greatly reduced. There are various indications that the radiation formed by supernova explosion is probably the cause of Megalodon's extinction. But so far, many people still believe that Megalodon has not become extinct. They think that only 5% of human beings have explored the ocean at present, and the remaining 95% is completely unknown, and Megalodon probably lives in this unexplored area.

However, there is still no substantial evidence for this conjecture. Theoretically, the food web structure in the current marine ecosystem can't support the existence of this predator at all, and larger carnivores like blue whales can't evolve smoothly. On the contrary, it is likely to be completely killed by Megalodon, and there has never been any incident in which Megalodon attacked ships since the birth of human civilization, so Megalodon should have been extinct long before human beings appeared.

It's not hard to imagine what a terrible thing it would be if Megalodon still exists today. Some people may ask Canglong, the ocean overlord, who is the king?

In fact, if we really want to win or lose, Canglong is probably no match for Megalodon. Although Canglong swims very fast and is a little taller than Megalodon, black dragon's bite force is only half of Megalodon's. In the face of absolute strength, they may not have a chance to defeat Megalodon at all.

But they don't belong to the same era. If the Canglong hadn't been extinct, Megalodon wouldn't have any chance to evolve. In fact, they all flourished in their own times. Now it seems that it doesn't matter who is strong and who is weak.
