Study Estimates Tyrannosaurus rex Body Temperature Comparable to Humans
Researchers have estimated the body temperature of the Tyrannosaurus rex at approximately 36°C (97°F), similar to humans, using a novel method analyzing rare isotopes in fossilized tooth enamel. Developed over a decade by UCLA scientists, this technique required significantly less fossil material, allowing the Natural History Museum of Los Angeles County to provide samples. The findings support the view that T. rex was warm-blooded, capable of active hunting in diverse climates, marking the first direct temperature measurement from its teeth.
