A team of scientists from the University of Missouri-Colombia has studied the conformation of the skull of a tyrannosaurus, trying to solve what is considered one of the mysteries of paleontology.

Paleontologists, in fact, have always wondered how the tyrannosaurus managed to break the bones of its victim and therefore bite so hard, without damaging the bones of the skull. According to Caleb Sellers, a researcher at the University of Missouri, this dinosaur had a huge mouth, more than 1.8 meters long, with which it could bite with more than six tons of force.

According to the same researcher, all previous studies of the problem did not take into account all the connections within the skull, including those between ligaments and cartilage. Using new imaging techniques, the team analyzed the anatomy and structural conformation of the tyrannosaurus skull and observed how the mouth reacted to chewing stress.

They also used models of those who could be considered two relatives of a tyrannosaurus, a gecko and parrot. The researchers concluded that tyrannosaurus skulls should have been more rigid than ever before, similar to the skulls of hyenas, crocodiles and inflexible skulls, such as lizards and birds, of two animals that are still direct relatives of the same dinosaur.
