( half times as long. T. rex's neck powe...)Fused nasal bones helped tyrannosaurids dismember prey

half times as long. T. rex's neck power was similarly staggering. For instance, in a split second, a T. rex could toss its head at a 45 degree angle and throw a 50kg person five metres in the air. And that's with conservative estimates of the creature's muscle force, says Snively. "We kept the muscle numbers down because we thought they couldn't possibly be that powerful, but Tyrrell museum colleagues showed that a T. rex's lower jaw could apply 200,000 newtons of force—that's like lifting a semi-trailer," he said. "All of the T. rex's features came together to give it the strongest bite of any land animal. The T. rex just blows everyone out of the water when it comes to strength.

"The fused nasal bones had been observed before, but no one but us and Emily Rayfield of Bristol hypothesized that the fusion enhanced the skull strength. Now we know it did."
