The bite of the Tyrannosaurus rex was four times stronger than previously estimated and equivalent to about three tons, reports Victoria Gill of the BBC.Scientists used a T. rex skull from the Manchester Museum and made a digital copy with a laser scanner. They then mapped jaw muscles and pressure sensors onto the digital T. rex.
To simulate a bite they virtually contracted the muscles with full force, measuring when the teeth hit each other.
The maximum force found was between 30,000 and 60,000 Newtons whereas previous studies estimated a T. rex bite as 8,000 to 13,000 Newtons (comparable to modern alligators).
T. rex was about 40 feet long, 15 to 20 feet tall and weighed 5 to 7 tons. It lived about 65-85 million years ago and ate meat, including other dinosaurs such as Triceratops.
