Ancient Shark Jaw Twist Reveals a Surprising Hunting Secret Lost for 370 Million Years
Ever wonder if sharks had a secret jaw trick up their sleeve before they became the toothy legends we know today? Well, buckle up—because this prehistoric predator, Ferromirum oukherbouchidates, didn’t just chomp; it rotated its jaw like some kind of oceanic Transformer, flicking out fresh rows of wicked teeth when it opened wide. Imagine losing a tooth and instead of just growing a new one straight up like modern sharks, this ancient beast sprouted a brand-new fang alongside the old, tucked inward by its tongue—and then flipped ‘em upright when it was dinnertime. Wild, right? It’s like the jaws had a mini workout routine designed purely for maximal carnage, turning every bite into a lethal feast. Talk about evolutionary innovation—why stick with boring old tooth regrowth when you can have a rotating killing machine? The discovery doesn’t just add a cool chapter to shark history; it flips our entire understanding of jaw mechanics way back in time, showing early sharks had some seriously savage upgrades to their biting game.

Researchers think the shark developed its rotating jaw to accommodate tooth regrowth.

Scientists have uncovered the remains of a prehistoric shark that once lurked in the waters of what is now Morocco. A new study on the shark fossils suggests that it possessed the terrifying ability to rotate its jaw, where a hidden row of sharp teeth jutted outward when its mouth opened to feed.
According to Live Science, this prehistoric shark called Ferromirum oukherbouchidates lived 370 million years ago. It was a ferocious predator of the ocean with an agile, slender body measuring about 13 inches long. It had a short triangular snout with unusually large eyes, with orbits taking up about 30 percent of its braincase’s total length.
