Prehistoric Predators – Megalodon (National Geographic HD Documentary)

Megalodon was the biggest shark ever to swim the oceans who ruled the seas for 20 million years. Megalodon is regarded as one of the largest and most powerful predators in vertebrate history. Fossil remains indicate that this giant shark reached a total length of more than 16 metres (52 ft), ferocious 50-ton animal that had a worlddwide distribution. Marine mammals were regular prey targets for super predator of the oceans. Many whale bones have been found with clear signs of large bite marks (deep gashes) made by teeth that match those of megalodon and various excavations have revealed megalodon teeth lying close to the chewed remains of whales, and sometimes in direct association with them. In this film scientist try to recreate Megalodon behaviour and predatory scenes based on scientific research.
