Tyrannosaurus rex had the most powerful bite of any creature that has ever walked the Earth, say scientists.

Previous estimates of the prehistoric predator's bite suggested it was much more modest - comparable to modern predators such as alligators.

This measurement, based on a laser scan of a T. rex skull, showed that its bite was equivalent to three tonnes - about the weight of an elephant.

The findings are published in the journal Biology Letters.

Dr Karl Bates from the biomechanics laboratory at the University of Liverpool led the research.

He and his colleague, Peter Falkingham from the University of Manchester, used the life-sized copy of a T. rex skeleton exhibited at Manchester Museum as a model for their study. "We digitised the skull with a laser scanner, so we had a 3-D model of the skull on our computer," Dr Bates explained.

"Then we could map the muscles onto that skull."

The scientists then reproduced the full force of a bite by activating the muscles to contract fully - snapping the digital jaws shut.

"Those [simulated] muscles closed the jaw as they would in life and... we measured the force when the teeth hit each other," Dr Bates explained to BBC Nature.

"The maximum forces we found - up at the [back] teeth - were between 30,000 and 60,000 Newtons," he said.

"That's equivalent to a medium-sized elephant sitting on you."

Previous studies had estimated that T. rex's bite had a force of 8,000-13,000 Newtons.

The researchers discovered how T. rex's bite force changed as it grew.

"Obviously, as its head got a lot bigger, there's an expected increase in bite force associated with that," Dr Bates explained. But for T. rex, the power behind its bite increased disproportionately - much more than would be expected from a "straightforward linear increase", he said.

This suggests that the predator's diet changed as it matured, and that perhaps only adult T. rex could have punctured the tough hide of another dinosaur.

See this guy?

HE WILL FUCK YOU UP.

 

[Slayven]

But what could it bench?

 

[CrazyDude]

T-Rex showing once again why it was the best dino.

 

[Dark Stalkers]

But what could it bench?

t-rex only squats

 

[sixteen-bit]

But what could it bench?

Probably not much.

I bet it was a squat monster though.

 

[Miggytronz]

DAT BITE.

 

[Impeccable]

 

[soul creator]

holy fucking shit, it's a dinosaur jesus chriiissst what the fuuuuuck

 

[dragonelite]

But what could it bench?

How can it bench with those skimpy arms.
But look at those legs he is definiatly a squatter.

 

[SPEA]

God. Dinosaurs are honestly the coolest thing ever. I wanna meet one some day :-(

 

[Montresor]

You should've saved that image for a velociraptor thread.

Fuck that movie was awesome

I know

Almost went with the guy on the toilet but chose this at the last second.

 

[jmdajr]

SWEET

 

[andycapps]

I kept on hearing around the time of Jurassic Park that the T-Rex had weak teeth or jaws or something. My faith in Jurassic Park and that it will one day come to pass has now been restored.

 

[BFIB]

T-Rex and the Stegosaurus were my favorites as a kid.

Remember when they thought the t-rex stood looked like this?

 

[Zwei]

There is a bloke from around my hood, called Rainbow Jeremy, that don't even believe in the existence of dinosaurs.

dinosaurs fossils were created by god to test our faith. carbon dating is somewhat inaccurate and there is no valid evidence to suggest that dinosaurs did exist.

Hi

 

[shinobi602]

Hi

Get that bird shit out of here.

 

[Sickboy007]

Hi

Even better.

Hi

The fuck is this

 

[bengraven]

The king is back.

Years of "he's a scavenger" or "he probably had sensitive skin" or more damning "there were many much bigger tyrannosaurs out there" and this.

The fuck is this

Sorry to shit on your childhood, but many dinosaurs, probably most especially late Cretaceous, had feathers. Probably not nearly this many however.

 

[Qwomo]

Feathers are up there with tipping and circumcision.

 

[Callo Merlose]

This only reenforces how strong King Kong's arms were.

 

[zomaha]

The fuck is this

Cold reality.

All of my old toys still say it does.

 

[MutFox]

I always thought the Mosasaur with it's terminator teeth would be stronger...
Though it does say "Walked the Earth"

Mosasaur swam.

 

[bengraven]

All of my old toys still say it does.

I had those toys too. And dollar stores still carry them because my kid still has them.

They're from molds from the late 60s that have never stopped being made. ha

 

[speedpop]

The fuck is this

Time to face reality. T-Rex was nothing more than a glorified monster chicken.

Bet those thighs would've been tasty.

 

[KO Traveling Hobo]

Hi

Where'd its arms go? And what's with the random coloring?

 

[Johann]

I thought Mega Shark and Predator X had greater bite force at over 150,000 newtons.

 

[Qwomo]

FWIW, the T-Rex didn't really have feathers. Probably. Maybe filamentous quills in a juvenile state in some species, but nothing like in that picture.

 

[strafer]

Malcolm was right...

 

[Forceatowulf]

Hi

LA LA LA I'M NOT LISTENING LA LA LA

 

[Instigator]

Bubububut... spinosaurus?

NO

They just found traces of feathers on one because it just massacred a giant bird and got hit with an asteroid right after

THIS IS A RAPTOR

I think the line "walked the Earth" sums it up.
The Ocean is scary.

I don't get why I'm supposed to hate the T-Rex with feathers.

That thing looks awesome.

I found a four year old estimated grid.

Bubububut... spinosaurus?

Rex had a wider, more stable jaw. Just because you're bigger doesn't mean you can bite stronger.

NO

THEY'RE ACTUALLY PRETTY SURE THAT T-REX'S TINY ARMS HAD FEATHERS ON THEM AT LEAST.

He used them for cleaning his teeth after a kill...the quills fit between them like floss.

/fake science

Bububububut T-Rex lost in JP3. I saw it happen.
