A new analysis of fossilized teeth from Thomas, a 17-year-old T. rex displayed at the Natural History Museum of Los Angeles County, reveals that the predator was a warm-blooded animal with an estimated body temperature of approximately 97.3°F. The study used isotopic chemical analysis to determine that T. rex's physiology was similar to mammals and birds, rather than cold-blooded reptiles. These findings provide strong evidence that theropod dinosaurs like T. rex were endothermic creatures capable of maintaining elevated body temperatures.
