T. rex had a body temperature of 36.3°C, almost the same as humans; fossil tooth chemistry reveals the 66-million-year-old predator was warm-blooded and could survive in cold climates

Now, a new study has taken the dinosaur’s temperature using chemistry locked inside its fossilised teeth, finding an average of about 36.3°C (97.3°F), strikingly close to the human norm. The research, published in Science Advances, offers…
