. "It carried that lipless look into pop culture to the point where we're now struggling to get rid of it."But by "lips," the researchers don't mean in the mammalian sense, neither plump and prominent nor muscular and able to be moved independently. Instead, the dino-lips were more like a static sheath meant to protect its threatening teeth.
"As any dentist will tell you, saliva is important for maintaining the health of your teeth," co-author Kirstin Brink, a paleontologist at the University of Manitoba, said in a. "Teeth that are not covered by lips risk drying out and can be subject to more damage during feeding or fighting, as we see in crocodiles, but not in dinosaurs."
Take Thomas Carr, a paleontologist at Carthage College and a recognized T-Rex expert, who argues that the study overestimates the enamel's importance in having robust fangs. Dentin, which forms an interior layer of teeth, is more crucial, he maintains.
