Tyrannosaurus rex bite force animated

In a new study published in UK journal Biology Letters, researchers at Liverpool University predict that a Tyrannosaurus rex’s bite is much stronger than previously thought. Researchers used laser scanners to digitize T. rex jaws and used computer models to reconstruct the jaw muscles of the T. rex and estimate its bite force. The study predicts T. rex had a bite force of 20,000 to 57,000 Newtons, equivalent to the force of a medium-sized elephant sitting down.
