Humans Have Something in Common With T. Rex
Newser • • science
Key Points:
- Scientists have determined the body temperature of Tyrannosaurus rex using chemical analysis of fossilized teeth, finding an average temperature of about 97 degrees Fahrenheit.
- This temperature is comparable to modern elephants and close to the average human body temperature, suggesting T. rex maintained a stable internal temperature.
- The study, published in Science Advances, used enamel atom patterns that vary with body temperature to make these determinations.
- Understanding T. rex's body temperature helps scientists infer its adaptability to different climates and the energy requirements for its prey and lifestyle.
- Researchers plan to apply this method to other dinosaurs to better understand their physiology and ecological dominance.
