Key Facts

• Researchers used chemical patterns in T. rex teeth enamel to estimate its body temperature.
• The study shows T. rex had a body temperature around 97°F (36°C).
• This temperature is similar to modern warm-blooded animals like elephants and humans.
• Earlier ideas suggested dinosaurs were cold-blooded, but evidence now supports they were warm-blooded.
• Knowing T. rex’s temperature helps scientists understand how it lived and survived in different climates.
• The study was published in the journal Science Advances.
• This method could be applied to other dinosaurs to learn about their biology.
• Scientists believe body temperature may have helped T. rex become a top predator in its time.
