Study finds T. rex was warmblooded, with human-like temperature
Researchers used fossil tooth enamel to estimate the dinosaur’s internal temperature, adding evidence that T. rex was warm-blooded and active.
- 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.

Tyrannosaurus rex Had Mammal-Like Body Temperature, Study Finds
A new analysis of Tyrannosaurus rex teeth indicates the ancient predator maintained a body temperature of about 36.3 degrees Celsius (97.3 degrees Fahrenheit), close to that of Indian and African elephants and far warmer than its cold-blooded reptile neighbors. The post Tyrannosaurus rex Had Mammal-Like Body Temperature, Study Finds appeared first on Sci.News: Breaking Science News.
Humans Have Something in Common With T. Rex
Using fossilized teath, scientists have finally taken the T. rex's temperature—and it wasn't too different from our own. Readings from three teath revealed an age body temperature of about 97 degrees Fahrenheit, per the AP. That's similar to modern elephants and close to the age body temperature of humans,...
Tyrannosaurus Rex Was a Warm-Blooded Dinosaur, With a Body Temperature Similar to That of Humans, Study Suggests
A tooth analysis hints that the fearsome predator ran at a toasty 97 degrees Fahrenheit. Maintaining that internal temperature may have allowed it to inhabit a range stretching from modern-day Alaska to Mexico during the Cretaceous period

News & RecordStudy shows T. rex was warm blooded
WASHINGTON — Using chemical clues in Tyrannosaurus rex teeth, scientists have shown that this massive predator was warmblooded — with a body temperature close to that of a person — in a finding they said should prompt a fundamental change…
According to a new study, T. Rex was definitely hot-blooded, hotter than a crocodile and colder than a chicken.
