Chomp on This, Chumps: The T. Rex Had the Strongest Jaws of Any Land Animal Ever

It's official. The Tyrannosaurus rex had the strongest flesh-and-bone slaughtering bite of any terrestrial animal alive or extinct. Doesn't that make you want to munch and suck down a raw steak while putting your arms inside your shirt and doing that T. rex tiny-hands thing?

Researchers at the University of Liverpool used a custom computer model that calculates, using an animal's skull, the range of sizes of the animal's jaw muscles. After calculating the likely shape of the T. rex's jaw muscles, they could approximate the physics of its bite as well. While previous estimates have pinned the T. rex bite force around 2000 pounds, which is comparable to a particularly large alligator, their new estimates went as high as 57,000 Newtons, which is about 6 tons of force. Time for some goofy analogies.

If the researchers’ high estimates are true, getting masticated by a T. rex is comparable to getting bitten by three great white sharks at once, or 6 alligators, or 30 snapping turtles. It's also like getting 2 hummers dropped on you, or having over 100 zombies (of the human variety) gnawing on your face.

But the authors are cautious not to say that the T. rex had the strongest bite of any animal ever. Extinct ocean predators, like the prehistoric white-shark-on-steroids Megalodon and the awkwardly-named ancient horror-beast, Predator X, likely had bites several times stronger than that of the T. rex, which is absolutely ridiculous Ok, I'm going to go eat some meat.
