Scientists Say T. Rex Had Three-Ton Bite

Posted on Feb 29, 2012

Here we see T. rex’s skull digitized to get a better sense of the prehistoric creature’s mighty bite.

And now for a brief bit of dinosaur geekery: Researchers at the University of Manchester had the fun job of putting together a computer model of a Tyrannosaurus rex skull that gave them a clearer idea about the bygone species’ bite, which turns out to be more impressive than previously believed.  —KA


Dr Karl Bates from the biomechanics laboratory at the University of Liverpool led the research.

He and his colleague, Peter Falkingham from the University of Manchester, used the life-sized copy of a T. rex skeleton exhibited at Manchester Museum as a model for their study. “We digitised the skull with a laser scanner, so we had a 3-D model of the skull on our computer,” Dr Bates explained.

“Then we could map the muscles onto that skull.”

The scientists then reproduced the full force of a bite by activating the muscles to contract fully - snapping the digital jaws shut.
