New Study Reveals T. Rex Had Lips Covering Its Teeth
TL;DR
Research suggests that the fearsome teeth of T rex may have been concealed behind a pair of thin, scaly lips, similar to lizards today. The perception that theropods were lipless arose because of the huge size of their teeth and because their closest living toothed relatives, such as crocodiles and alligators, do not have lips. The study found that the teeth of tyrannosaurs often lasted more than 12 months before being replaced, adding weight to the idea that they had lips. However, the case is not yet closed, and further research is needed to confirm the findings.
