T-rex's bite force equals weight of three cars: Study

A study on Tyrannosaurus rex by US-based scientists has revealed that the dinosaur could produce biting forces equalling the weight of three small cars (about 3,600 kg). Further, its conical teeth could generate "astounding bone-failing" pressures to drive open cracks in carcasses of large horned dinosaurs, scientists said. Researchers carried out the study using models of crocodiles and birds.
