Researchers have analysed the jaw mechanics of young and adult tyrannosaurids to uncover how they bit into their prey. Their analysis suggests that younger tyrannosaurs were incapable of delivering bone-crushing bits, and that adults were much better at tearing out chunks of flesh from their prey. Their analysis suggests that adult tyrannosaurs could deliver bone-crushing bites of up to 60,000 Newtons – significantly stronger than an adult lion, which bites down on its prey at around 1,300 Newtons. However, the teen tyrannosaurs were incapable of delivering such strong bites, as their jaws were smaller and less deeply set, according to the researchers. 'Adult tyrannosaurs were likely subduing large dinosaurs such as the duckbilled hadrosaurs and Triceratops, which would be quickly killed by their bone-crunching bite.
