Scientists have taken the temperature of a Tyrannosaurus rex, 66 million years after it lived. A UCLA-led team analyzed chemical bonds preserved in fossil tooth enamel and estimated that the predator ran at about 97 degrees Fahrenheit (36 degrees Celsius). That is similar to modern elephants and close to the human range. The results were published Sept. 16 in Science Advances.
