Analysis of a 66-million-year-old tooth indicates the dinosaur maintained a body temperature of 97 degrees. This evidence suggests the predator operated with a high metabolic rate rather than relying on external heat sources. The findings align the T. rex's thermal profile with modern endothermic mammals, challenging older views of dinosaur physiology.Why it mattersDetermining whether dinosaurs were cold-blooded or warm-blooded affects understanding of their growth rates and ac
