Tyrannosaurus rex had human-like body temperature
Summary and headline written by AI from the source article. How we work
Scientists studying fossils in North America determined Tyrannosaurus rex maintained an average body temperature of approximately 36 degrees Celsius.
Researchers from the University of California, Los Angeles, and other institutions analyzed three T. rex teeth to arrive at this finding. They discovered that patterns in the arrangement of atoms within the tooth enamel reflected the dinosaur’s body temperature during its life.
Previous theories described dinosaurs as slow, lumbering, and cold-blooded, but later discoveries suggested some dinosaurs regulated their own body temperature. The new research supports the idea that Tyrannosaurus rex was warm-blooded, similar to modern elephants and humans. Understanding the body temperature of T. rex helps scientists learn more about its life, including its geographic range and hunting habits. A stable internal temperature would have allowed the dinosaur to thrive across varied climates and maintain energy levels while pursuing prey.
The team published their findings in the journal Science Advances.
