Introduction to the ancestor of the megalodon, the megalodon

The megalodon may have the strongest bite found in the history of Earth, with a maximum estimate of about 20 tons, and its oral bite power exceeds that of a Tyrannosaurus rex, allowing it to easily crush a whale's ribs. Living from the Late Miocene 15 million years ago to the Early Pleistocene 2.6 million years ago, it was the apex predator of the ocean. They have been hailed by many paleontologists as the most powerful creatures in the history of the planet.

Because sharks are cartilaginous fishes, it is difficult to leave fossils on ordinary bone parts, so as of 2013, only some of its palm-sized triangular teeth and a few fossils of vertebrae have been found. Adult megalodon teeth are generally 10-16 cm long and more than 18 cm long, which is several times longer than the teeth of great white sharks. Although no complete fossil of the upper and lower jaws has been found, scientists have calculated that the shark is about 20 meters in size, weighs about 90 tons, and has a mouth with a large mouth that can reach a diameter of one meter.

Megalodon. The ancestor of the whirltooth shark was the whirling tooth shark. But both megalodons and whirltooth sharks were extinct in ancient times.

The megalodon lived in the Cenozoic oceans 28 million to 1.5 million years ago and is a long-lived species. The shark family in which they belong is an "evergreen" in the history of life evolution, which appeared at least 100 million years ago, and is older than the qualifications of dinosaurs. Over the years, sharks have endured many environmental upheavals and faced ichthyosaurs.

Threats from other predators, such as dragons and cetaceans, still dominate the top of the marine food chain, with more than 300 species.

Although the megalodon is extremely capable of hunting, it is mainly a whale.

For food, and at that time, the sea temperature at the poles may be getting lower and lower, not only is it not suitable for the survival of the megalodon, but the water cycle also leads to a decrease in upwelling, and a large number of whales are dying, so that the life of the megalodon is becoming more and more difficult, and it is finally eliminated by nature, but it still leaves the great white shark.

This species continues to write its legend in the ocean.

Megalodon, which means "big tooth" in Greek. This shark is about 19 meters in size and weighs about 60-80 tons. In 2013, a complete fossilized skeleton of a megalodon was discovered, with a vertebrae much larger than those of a great white shark, and it is estimated to be 18-19 meters.

Weighing 60-80 tons, recent studies have proven that its largest individual could be 100 meters long Some believe it is 23 meters, but no fossilized bones up to 23 meters long have been found so far. The megalodon is the most powerful creature ever found to bite in the history of the planet, with an average bite force of 28 tons and a maximum bite force of 36 tons, and its tooth biting power far exceeds that of Tyrannosaurus rex. For the only time in history, sharks have taken the unshakable top of the ocean, and the lowest vertebrate fish prey on cetaceans with far higher IQs than they do.

It is easy to bite the hardest skull of a whale. Living from the Late Oligocene 28 million years ago to the Early Pleistocene 1.5 million years ago, it was the ultimate predator of its age. They have been hailed by many paleontologists as the most powerful creatures in the history of the planet.

The megalodon cannot reach a maximum of 15 meters, it can reach a maximum of wireless.

The megalodon no longer exists, it is extinct. Megalodons are fearless and rampant in the ocean. Whales and other sharks, at least in terms of absolute combat effectiveness, are no match for megalodons, and are even likely to become their prey.

In the ocean, the megalodon hardly has any natural predators.

However, just about 3 million years ago, this terrifying creature gradually became extinct and disappeared from the stage of history.

Megalodon habits:Megalodons can hunt any creature in the sea, but they prefer to hunt cetaceans the most.

Other marine mammals are also on its plate. Adult megalodons hunt in the open ocean, while juveniles live closer to shore. Megalodon had no predators at the time, only rivaled by Melville's whale, which was also an apex predator.

Megalodon. The mouth can reach two meters in diameter and has a strong, streamlined body.

Megalodons can hunt any creature in the sea, but they prefer to hunt cetaceans the most. Other marine mammals.

It's also a dish on its plate.

Adult toothed sharks hunt in the open ocean, while juveniles live closer to offshore. Megalodons attack animals that ventilate at the surface of the sea.

Extinction theory

There are theories that since the megalodon mainly feeds on cetaceans, the sea water at the poles is not suitable for the survival of the megalodon, whales.

As a result, it can escape the predation of megalodons, which become extinct due to lack of food.

Other interpretations consider anything to the food chain.

About 1.5 million years ago, the Earth's water cycle.

There are changes, upwelling is reduced, a large number of cetaceans are dying due to lack of food, and there are fewer diverse whale species), all of which will be eliminated by predators with huge metabolic needs. However, a few scientists have pointed out that the megalodon is still extinct and is still alive today.
