Megalodon: The Largest Predator That Ever Lived The Megalodon shark is considered the largest predator that has ever lived. To compare its size, if we were to compare it with the Great White shark, the Megalodon was nearly three times as long and 20 times heavy as the Great White shark. The very earliest megalodon fossils date back to 20 million years ago. For the next 13 million years, this breed of shark dominated the ocean colonies until becoming extinct just 3.6 million years ago. Experts reveal that Megalodon wasn’t only the giant shark globally but one of the largest fish that ever existed. This is why people and fossil enthusiasts are looking for Black Megalodon teeth online. The fascination of Megalodon’s tooth is based on the fact that it reaches the size of around 10 cm long. Therefore, these teeth perfectly illustrate what these massive animals ate and lived. Their Teeth Reveal A Story Experts reveal that with its large serrated teeth, Megalodon is known to eat meat, most likely whales and large fish. Their prey is also supposed to include dolphins and as large as humpback whales. Some found fossils showed cut marks of megalodon teeth etched in the surface. Others tend to include the tips of teeth broken off in a bone during a feeding frenzy that must have occurred a million years ago.
