The T. Rex Had a Body Temperature Similar to Our Own, Study Finds – WTOP News
- On Wednesday, a study published in Science Advances confirmed the Tyrannosaurus was warm-blooded, with an internal body temperature of about 97 degrees Fahrenheit, settling a long-standing paleontological debate.
- Researchers at UCLA achieved this measurement by analyzing rare carbon-oxygen bonds in tooth enamel from Thomas, a 34-foot Tyrannosaurus, using techniques refined to require only milligrams of material.
- This internal temperature helps explain how the apex predator maintained an active hunting lifestyle and thrived across diverse North American environments, including cooler regions like Alaska.
- While the Tyrannosaurus's 97-degree temperature sits between cold-blooded reptiles and hotter avian descendants ranging between 104 and 109 degrees Fahrenheit, the data confirms the predator was endothermic.
- Geobiologist Robert Eagle, who led the project for 15 years, hopes to apply this precise method to reveal metabolic details of avian dinosaurs and ancient mammalian ancestors next.

T. rex was warm-blooded and had body temperature close to ours, study finds
Using fossilised teeth, scientists have finally taken the T. rex’s temperature – and it wasn’t too different from our own. Researchers once thought that dinosaurs were sluggish, cold-blooded creatures. Later findings challenged that, suggesting that older dinosaurs were warm-blooded and could control their body temperature. Most scientists agree that Tyrannosaurus rex was warm-blooded, but pinning down the exact core temperature of an extinct cr…
Fossil tooth analysis confirms Tyrannosaurus rex was warm-blooded
By Taylor Nicioli, CNN (CNN) — Scientists have suspected for nearly 60 years that Tyrannosaurus rex was warm-blooded.When a fossilized footprint of T. rex turned up in Alaska in 2022, it added to the evidence that these predators could thrive in frigid environments, where most cold-blooded reptiles could not. Now, researchers have put a number
UCLA Study Finds T. Rex Body Temperature Similar to Humans
UCLA scientists reported Wednesday they have determined the body temperature of Tyrannosaurus rex for the first time, using fossilized teeth to calculate that the dinosaur had a temperature of about 97 degrees Fahrenheit — roughly comparable to humans. The findings, published in the journal Science Advances, provide further evidence that T. rex was warm-blooded and […]
Writing Science, 16 Sep (EFE).- Tyrannosaurus rex was a hot-blooded dinosaur, with an estimated body temperature of about 36.3 degrees, according to an analysis of the tooth enamel of fossil teeth, so it would have been an active animal, hunting or feeding carrion to nourish its fast metabolism.The discovery that [...] The entry The Tyrannosaurus rex was of hot blood and is known for its teeth was first published in HolaNews.
The T.rex was the biggest land predator of all time. For a long time, however, it was thought to be a sluggish, change-warm giant, similar to today's crocodiles. However, researchers now assume that it was an agile warm flower. An analysis of his teeth confirms this now.
