The death smile of the tyrant dinosaur

Paleontologists have claimed to have discovered the mystery behind the "deadly smile" of Tyrannosaurus rex the dinosaur, which dominated the Earth 65 million years ago.

>>>Tyrant dinosaurs have tens of times the bite

Previously, T-rex dinosaur research groups often only noted the 'terrorist' size of the teeth that created the strongest blow in the history of the biological world.

Now, the expert team of the University of Alberta (Canada) discovered that besides the difference between the teeth of T-rex jaws, their teeth also have different jagged structures.

Before attacking, T-rex often "smiles" at its prey

'The variety of sharpness of teeth not only allows T-rex to be able to chop meat and crush bones with a single tap, but also helps the dinosaur to eat more easily, ' according to the quoted Science Daily. research leader Miriam Reichel.

The analytical results show that the front teeth of T-rex are responsible for the bite and drag, while the teeth along the jaw line pierce and tear the flesh. And the tooth that lies deep inside not only cuts the meat into small pieces but also puts food down the throat.

Reichel said the study contributed to confirming the placement of tyrannosaurid dinosaurs in various specialized toothed organisms.

An unexpected point is that T-rex's teeth are not as sharp and sharp as the teeth of the same type, but they are the strongest.
