The theories of extinction

Some scientists hypothesize that the increase in competitors may cause the number of Megalodon super sharks to decline. For example, killer dolphins, which forage in groups, have a predation that is superior to Megalodon's independent predatory behavior. The team of scientists think that the giant prehistoric predator died out 3.6 million years ago. This means that Megalodon's extinction is unrelated to the extinction of ancient seals, walruses, manatees, dolphins, and whales about 1 to 2.5 million years ago.

Instead, the newly evolved great white shark Carcharodon carcharias likely played a role in Megalodon's extinction. Great white sharks are now known as fearsome predators. However, Megalodon can reach three times the size of the largest great white shark ever recorded. It sounds strange that smaller sharks can compete with much larger fish; However, other experts also support this hypothesis.
