A new study has found that the T. rex’s body temperature was similar to humans. Most scientists agree that the fearsome predator was warm-blooded, but pinning down its exact body temperature has been difficult. In a new study, researchers hunted for chemical clues in Tyrannosaurus rex teeth, studying how atoms within the enamel clumped together. They came up with an average temperature of 97 degrees Fahrenheit, which is similar to the temperatures of modern elephants and humans. Knowing how hot or cold T. rex was can help scientists piece together how the dinosaur might have lived. The findings were published Wednesday in the journal Science Advances.
