No longer exists.
Extinction theory:
1. Some theories point out that because the megalodon feeds primarily on whales, the water at the poles has become colder and is therefore unsuitable for whales to survive. can escape megalodon predation, causing the megalodon to become extinct due to lack of food.
2. The reason for its extinction is assumed to be that around 1.5 million years ago the Earth's water cycle changed and upwelling decreased. Due to lack of food, a large number of whales died and the number of whales died. various species of whales declined, the megalodon could not find enough food and gradually disappeared.
3. Over a long period of time, like other creatures, it is possible to gradually evolve into other sharks. Some ancient creatures did not disappear but gradually evolved into new ones.l species, just like the birds of the jungle have transformed into chickens.
Detailed information
1. Appearance Characteristics
As sharks are cartilaginous fish, it is difficult to leave fossils in the general skeletal parts. Thus, since 2013, only a few fossils of triangular teeth as large as the palm of the hand and a few fossils of vertebrae have been found.
The teeth of the adult megalodon are generally between 10 and 16 cm long, with the longest measuring over 18 cm. Although complete fossils of the upper and lower jaw have not yet been found, scientists have calculated, based on the size of its teeth, that the shark is approximately 19 meters long, weighs approximately 70 tons, and has a mouth up to 2.8 meters in diameter.
2. Life habits
The megalodon can attack any sea creature, but it prwants to attack whales. Other marine mammals also feed it.
Adult megalodons hunt in the open sea, while young ones live closer to the coast. The megalodon had no natural enemies at the time, except for Melville's whale, which was also the megalodon's main predator.
3. Range
A giant shark that lived about 28 million to 1.5 million years ago. According to whale fossils found in various locations, there are scars caused by megalodon attacks. It appears that this shark was once widespread. The extinction of the megalodon remains a mystery.
