T. rex bite strongest of all land animals

BBC : Contrary to previous estimates, which suggested that the bite of a Tyrannosaurus rex was comparable to that of modern predators, the dinosaur’s bite exerted 3–6 tons of force, or 10 times the force of an alligator bite. Karl Bates of the University of Liverpool and Peter Falkingham of the University of Manchester created three-dimensional scans of an adult and a juvenile T. Rex, then mapped the muscles onto the scanned images. By digitally manipulating the muscles in the image, they were able to replicate the animal’s bite. Bates and Falkingham’s findings are published in Biology Letters .
