T-rex bite was world's strongest: Study

Tyrannosaurus rex, the largest known land carnivores of all times, also had the most fearsome and powerful bite than any other creature that ever roamed on Earth, a new study has found.

Previous research on the prehistoric predator’s bite had suggested that it was much more modest that can be comparable to modern predators such as alligators.But the new findings, based on a laser scan of a T-rex skull and published in the journal Biology Letters, showed that its bite was equivalent to three tonnes, about the weight of an elephant.

“Our results show that the T-rex had an extremely powerful bite, making it one of the most dangerous predators to have roamed our planet,” study author Karl Bates, of the University of Liverpool, was quoted as saying by LiveScience.

Younger T-rexes didn’t have such strong bites, which probably meant that they had a different diet and relied less on the fearsome bite than their older counterparts.

This differing diets likely led reduced competition between generations of T-rex, the researchers said. The new estimate of bite force is higher than past estimates that relied on indent measures in which they pressed down the skull and teeth onto a bone until they got the imprints that matched those on fossils.

In the new study, the researchers created a computer model of the dinosaur’s jaw by first digitally scanning skulls from an adult and juvenile T-rex, an allosaurus, an alligator and an adult human. They used these scans to model each animal’s bite. “We took what we knew about T-rex from its skeleton and built a computer model,” Bates said. “We then asked the computer model to produce a bite so that we could measure the speed and force of it directly.”
