A study said the predator's teeth were probably mostly covered and did not stick out. The better to kiss you with? The Tyrannosaurus rex may have had scaly lips that covered their teeth. Researchers said depictions of the predator with giant flashing teeth, fully visible, might be incorrect. In a study published Thursday in the journal Science, paleontologists compared skulls and living reptiles. Their findings distorted the image of the classic "Jurassic Park" series, finding that the teeth on the T. rex and other big theropods were likely covered by the lips. The teeth did not stick out when its mouth was closed, with just lips visible even in a wide open bite. BIGGEST PENGUIN IN HISTORY WAS 'MONSTER BIRD,' WEIGHED OVER 300 POUNDSSome large monitor lizards actually have bigger teeth than T. rex compared to their skull size and can still fit them under a set of scaly lips, according to study author Thomas Cullen, a paleontologist and assistant professor at Auburn University."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," he said in a release from the university. "The teeth of these theropod dinosaurs did not experience wear and tear like a crocodile, and most likely had a lip-like covering."Examining wear and tear on teeth also pointed to these conclusions. Analyzing a tooth from T. rex relative Daspletosaurus, it was found to be in good condition and did not show an uneven damage pattern – something exhibited in creatures with teeth sticking out of their mouths. "This changes our perceptions about the appearance and oral configuration of these iconic predators and has broad implications for our interpretations of other terrestrial animals with large teeth," the authors said.CHRISTIE'S PULLS T.
