Join over 250,000 others to get the top stories curated daily, plus special offers! Then comes the Great White, but comparing terrestrial and aquatic species does not have much merit. That’s the conclusion of a new analysis of the giant predator’s chomp. Bite force is measured in Newtons, a unit of measurement named after physicist Sir Issac Newton, famous for formulating the theory of gravity. Previous studies have estimated that T. rex 's bite had a force of 8,000 to 13,400 Newtons, but given the size of the animal, thought to weigh more … "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," Bates said in a statement. Spinosaurus' mainly ate fish and had a thin, elongated jaw, with thin, hollow, sharp teeth, and a weak bite force.

I have no idea what the bite would do to an animal beyond hurt a lot, Karl Bates, co-author of the study and post-doctoral researcher in biomechanics at the University of Liverpool, told Discovery News. Using the jaw musculature of modern crocodiles, Florida State University researchers calculated that the T-rex might have had a bite force of 8,000 lb (35,586 N), and 431,000 psi The extinct sharks could bite with a force three times stronger than that of a T. rex - 105,000 to 171,000 Newtons - according to National Geographic. Scientists previously thought that the massive dinosaur bit with much less powerful force, estimating that the T. rex had a bite force between 8,000 and 13,4000 Newtons. — A powerful bite, strong teeth and repeated crunching. I think everyone expected T. rex to have a strong bite force, but it's even stronger than we expected, Bill Sellers, a computational zoologist at the University of Manchester who was not involved in the study, told BBC. Previous studies have estimated that T. rex’s bite had a force of 8,000 to 13,400 Newtons, but given the size of the animal, thought to weigh more than 6,000kg, researchers suspected that its bite may have been more powerful than this. When Bates and Falkingham used computer models to simulate T. rex’s bite, the result was “quite surprising,” Bates told us: a maximum bite force of … The king of dinosaurs could bite down with a force of 7,800 pounds-force (34,522 newtons), a force equal to the weight of three small cars, the researchers found..

Falkingham argue that the meat-eating T-rex had a fearsome bite, estimating that the bite of the dinosaur was anywhere between 35,000 to 57,000 Newtons at a single tooth, comparatively much larger than the force behind the bite of the alligator, which is considered to have the strongest bite force of any modern animal. Juvenile T. rexes probably had a much weaker bite, making it likely that the dinosaur's diet changed over time, the authors wrote. 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. The massive skull of the Tyrannosaurus rex or "tyrant lizard king" measured 1.5m in length and was balanced by its long, heavy tail. It had the biggest bite force of any terrestrial animal in history. The already fearsome Tyrannosaurus rex dinosaur may have been even deadlier than previously thought.
