Tiranozaurul, „un animal mult mai mobil și adaptabil”. Ce au descoperit cercetătorii analizând dinți de T.rex

Researchers have found that Tyrannosaurus rex had a warm-blooded physiology, with a body temperature similar to that of humans. This discovery challenges the long-held belief that T. rex was a sluggish predator. The study analyzed the chemical composition of T. rex teeth, revealing an average body temperature of 36.3 degrees Celsius. This suggests that T. rex was more mobile and adaptable than previously thought, capable of thriving in various climates. The findings indicate that warm-blooded animals require more food, implying T. rex had higher metabolic needs. The research utilized a minimally destructive technique to analyze tooth enamel from well-preserved specimens.
