A Megalodon is an extinct species of shark that lived approximately 28 to 1.5 million years ago, during the Cenozoic Era. It's regarded as one of the largest and most powerful predators in vertebrate history. Fossil remains suggest that this giant shark reached a maximum length of 15.9–20.3 metres (52–67 ft). Scientists suggest that C. megalodon looked like a stockier version of the great white shark.
