Baby shark! Newborn megalodons larger than humans, scientists say

Creatures that patrolled the oceans 3m years ago were about two metres long at birth, researchers find

Enormous megatooth sharks, or megalodons, which patrolled the world's oceans more than three million years ago, gave birth to babies larger than most adult humans, scientists say.

Researchers made the unsettling discovery when they X-rayed the vertebra of a fossilised megalodon and found that it must have been about two metres (6.5 ft) long when it was born.
