Did the Tyrannosaurus rex just become less scary?
AUBURN, Ala. - Auburn University’s Thomas Cullen is part of an international collaboration of researchers that has uncovered evidence that contrary to popular belief, theropod dinosaurs like the Tyrannosaurus rex and Velociraptor had lips that covered their teeth.
“We reconstructed soft tissue anatomy, compared dental measurements, and studied dental health and wear records to further uncover that what you are used to seeing on the big screen is not accurate,” Cullen said. “The teeth of these theropod dinosaurs did not experience wear and tear like a crocodile and most likely had a lip-like covering.”
Overall, these new results create an invaluable framework that impacts dinosaur paleontology and studying the structure of ecosystems. Traditionally, animations and CGI of famous T. rex and Velociraptor dinosaurs in blockbuster movies like “Jurassic Park” have featured the animals with their teeth exposed and on display at all times.
According to the researchers, the theropods’ lips were more similar to lizards and were not like the lips of mammals or humans.
