Rex's bone-shattering bite was much worse than its bark

T. rex jaw

"Having high bite force doesn't necessarily mean an animal can puncture hide or pulverize bone, tooth pressure is the biomechanically more relevant parameter".

Researchers from Florida and Oklahoma state universities investigated the teeth and bite mechanism of the T. rex to understand how the dinosaur, which stood about 15 to 20 feet tall and measured 40 feet from head to tail, exerted 8,000 pounds of force with its bite. The Palo Alto, California-based company said the prototype contains 160 terabytes of memory, capable of managing the information from every book in the U.S. Library of Congress five times over.

For this research, the team, from Florida State University, build on previous models they had created to study how the musculature of living crocodilian species contribute to bite forces. They can swallow bones if they are not too large, but are unable to crush them with their teeth.

At the same time, their long, conical teeth generated an astounding 431,000 pounds per square inch of bone-failing tooth pressures. Once the models were complete, they observed how the T. rex would have bitten down on prey, discovering just how insanely powerful the animal's jaws really were.

T. rex probably held whole limbs in its mouth as it gnawed. "If you look at T. rex, it's a total anomaly compared to all other meat-eating dinosaurs", paleontologist François Therrien told The Washington Post.

Bone crushing-extreme osteophagy in the scientific parlance-is a trait exhibited by just a handful of mammalian scavengers and predators today, including the spotted hyena and the gray wolf. "It's not much different than when we bite down on a drumstick", Gignac said, "though we go for flesh, not bone". Other carnivorous animals such as hyenas and wolves can also break and consume bones.

The T. rex's teeth inflict an even bigger damage.

To begin, the researchers developed and tested a 3D anatomical model that predicted the bite forces of the American alligator (Alligator mississippiensis).

The giant Tyrannosaurus rex pulverized bones by biting down with forces equaling the weight of three small cars while simultaneously generating world record tooth pressures, according to a new study by a Florida State University-Oklahoma State University research team. "We have modeled bite forces for giant fossil crocs at 23,000 pounds, so [T-Rex] was not the king in that regard", Erickson says.

Popular Science explains the two numbers: Bite force (the 8,000-pound figure) refers to the force exerted by the jaw, but that's only half the story. Also, the animal had more than 30 teeth in the upper jaw alone.

They based the T. rex model on a computed tomography (CT) scan from a scaled replica of one of the best-preserved skulls.

The dinosaur's ferocious bite would have helped it splinter the carcasses of large horned dinosaurs and duck-billed hadrosaurs, whose bones were rich in mineral salts and marrow, Gignac said. In reality, some studies suggested that the T. rex might have been more of a scavenger, feasting mostly on dead prey as it was easier to obtain.
