Once the largest known carnivore on land, Tyrannosaurus rex also had the most powerful bite of any terrestrial animal of any time period, a new study suggests.
To see how forcefully T. rex could bite, biomechanicists involved in the new study used laser scanners to digitize juvenile and adult T. rex skulls. The team then used computer models to reconstruct the dinosaur’s jaw muscles and analyze bite performance.
The models suggest that an adult T. rex was capable of a maximum bite force of 35,000 to 57,000 newtons at its back teeth. That’s more than four times higher than past estimates and several times as forceful as the bite of a modern crocodile. Learn more here.
