Reality and fiction: scientists came to the conclusion that tyrannosaurs were not the same as shown in the movies

Reality and fiction: scientists came to the conclusion that tyrannosaurs were not the same as shown in the movies
To prove that the giant lizards were different from their movie images, scientists analyzed their teeth. And they came to the conclusion that the latter "were not put on display", but were hidden behind the lips.

If you recall most of the reconstructions, then the Tyrannosaurus rex (Tyrannosaurus rex) is depicted as a giant lizard that frightens with its sharp teeth. But an international team of researchers has proven that this appearance is not true. Scientists claim these fangs were hidden behind thin scaly lips.
To reach this conclusion, the researchers had to analyze the museum exhibits of various theropods, carnivorous lizard dinosaurs, which include tyrannosaurs. They paid special attention to the signs of wear on the enamel of the teeth of dinosaurs and crocodiles, which are considered the closest modern relatives of theropods.
The enamel of the teeth must remain moist, otherwise it begins to crack. In crocodiles, it is thick and stays hydrated because they live in water. But this did not prevent scientists from finding traces of cracks on the outer surface of the teeth of these reptiles.
As for the teeth of theropods, no damage was found in them. The scientists concluded that they had lips that protected their teeth and kept them moist with saliva while their mouths were closed.
