Fossilized Teeth Reveal T. Rex Maintained Body Heat Comparable to Humans

Analysis of fossilized teeth has enabled scientists to measure the body temperature of T. rex for the first time, revealing values remarkably similar to those of modern humans.

For decades, paleontologists presumed dinosaurs were slow, cold-blooded reptiles. Subsequent research challenged this view, indicating that mature dinosaurs possessed warm-blooded metabolisms capable of regulating internal temperature.

While the scientific consensus now holds that Tyrannosaurus rex was endothermic, determining the precise core body temperature of an extinct predator remains a significant challenge.
