Scientists have proposed a new look for the famous Tyrannosaurus Rex dinosaur, suggesting that it had lips and proportionally sized teeth that were concealed by these lips.
The research, conducted by an international team of researchers from the University of Portsmouth and published in the journal Science, examined the jaw morphology, tooth structure, and dental wear patterns of lipped and lipless reptiles.

Contrary to previous theories, the study showed that T-Rex lips were more similar to those of lizards than crocodiles. The researchers found that the teeth and skulls of T-Rex were similar in size to those of contemporary lizards with lips, with pores in the theropod jaws that would have contained nerves and blood for the mouth tissue much more like those in a lizard than a crocodile.
The study provides novel insights into how the T-Rex may have nourished and preserved dental health and opens up new research directions for evolutionary ecologists and artists.
