Tyrannosaurus rex bite measured
Scientists have digitally recreated the snapping jaws of Tyrannosaurus rex.
Their new simulation has revealed that the giant predator had the most powerful bite of any creature that ever walked the Earth.
The team have published their findings in the journal Biology Letters.
Here, Dr Karl Bates from the biomechanics laboratory at the University of Liverpool, who led the research, explains how his study revealed how powerful T. rex's jaws actually were.
