The T. rex had a body temperature similar humans, study finds
New York Post • • science
Key Points:
- Scientists have determined the body temperature of Tyrannosaurus rex using chemical analysis of fossilized teeth enamel, revealing an average temperature around 97°F (36°C), similar to modern elephants and close to human body temperature.
- This finding supports the idea that T. rex was warm-blooded, challenging earlier beliefs that dinosaurs were cold-blooded and sluggish.
- The research, published in Science Advances, utilized atom clustering patterns in tooth enamel that vary with body temperature to estimate the core temperature of the extinct predator.
- Understanding T. rex's body temperature helps scientists infer its ability to live across diverse climates and its metabolic needs, which may have contributed to its success as a top predator.
- Researchers suggest applying this method to other dinosaur species to better understand their physiology and ecological roles during the dinosaur era.
