Extinct megalodon shark was even bigger than previously thought

Fifteen million years ago, now-extinct species of dolphins, whales and large sea cows roamed the world’s oceans, topping the underwater food chain. Yet back then, any one of these creatures could become prey to the ocean’s fiercest apex predator: the megalodon, a giant shark with massive teeth and a body the size of a whale.

In many ways, the so-called “monster shark” is regularly featured in TV marathons like “Shark Week” while spawning horror films like “The Meg.” But the true size and shape of this extinct giant probably doesn’t resemble the star of “Jaws.”
