Tyrannosaurus Rex could destroy a car with teeth.
He taunted six tons of pressure on his unfortunate victims.
But although more evidence supports this assessment, there is debate about how he did it because he had a loosely coupled skull.
Recent studies show that the bones of the skull must have been fixed and solid animal had a chilling bite. – T-Rex was just one of those optimal built animals.
Had giant jaw muscles and effectively assumed the muscle strength and used for prey, because he had a hard skull – said co-author of the study, Casey Holliday, a paleontologist at the Medical Faculty of the University “Missouri.”
This is different from the skulls of mammals, like ours, where there are only two parts: the part that holds the brain and the lower jaw – said Holiday.
However, the idea that you had a flexible-Rex skull a mathematical problem. – When you have a giant skull as you-Rex who bites with great force … if you have built flexibility into the system, you will face many failures.
You will need to download the full force of the muscles and joints in the spoils through teeth – said Holiday.
To test the idea, Holliday and her former student Ian Bone, now an assistant professor at the college, “Albright” in Reading, Pennsylvania, created digital models of the skull you-Rex.
The team discovered that dinosaur efficiently applied pressure when the joints in the upper part of the skull largely remained motionless. –
The face and skull-Rex they were not able to move.
This supports our conclusion that the bones of the mouth did not move when the dinosaur will CASS prey – said Costa.
This means that better use the full force of the jaw muscles than his ancestors or relatives with moving palates.
Tyrannosaurus are unusual because their teeth are strongest in front of the mouth, unlike predators like crocodiles, whose strong teeth located in the back.
