The Size and Power of Megalodon
Megalodon is recognized as the largest predator to have ever existed, measuring approximately 18 meters in length and weighing around 50 tons. Its enormous jaws, which could reach a width of three meters, were lined with 272 teeth, each measuring around 20 centimeters long. The creature's size and predatory capabilities positioned it atop the oceanic food chain roughly 16 to 3 million years ago, a time referred to as the 'lost Serengeti of the sea.' This era featured a diverse array of marine life, with Megalodon possibly preying on large marine mammals, illustrating its dominance in a world rich with potential prey.
