Quick answers

What was the T. rex's body temperature?

97 degrees

How did scientists determine the T. rex's body temperature?

By analyzing the dinosaur's teeth, which contain traces of oxygen and carbon isotopes

Is this discovery significant?

Yes, it challenges previous theories about dinosaur physiology and suggests that the T. rex was warm-blooded

The brief

⚡ Executive Intelligence Takeaways Corroborated across 6 independent newsrooms

Velocity & Diffusion: Coverage exploded across 6 distinct news outlets with 6 published articles, achieving a live velocity of 18.
Primary Driver: Scientists confirm the T. rex had a body temperature of 97 degrees.
Source Integrity: Verified strictly against primary headline reporting under zero-hallucination protocols.

This contradicts previous assumptions that dinosaurs were cold-blooded. The study's findings are based on analysis of the T. rex's teeth, which contain traces of oxygen and carbon isotopes that indicate a warm-blooded metabolism.

The New York Times and Los Angeles Times report that the study's results confirm the T. rex was warm-blooded, while AP News notes that this means the dinosaur's body temperature was similar to our own. Popular Science highlights the significance of this discovery, stating that it challenges previous theories about dinosaur physiology.

The study's findings do not address the T. rex's growth rate or how its body temperature varied throughout the day.
