Tyrannosaurus rex avea sânge cald, arată un nou studiu

Recent studies reveal that Tyrannosaurus rex had a warm-blooded physiology, with an internal temperature similar to humans, around 97 degrees Fahrenheit. This challenges previous beliefs that all dinosaurs were cold-blooded. Advances in technology allowed scientists to measure the blood temperature through chemical bonds in fossilized teeth. The findings suggest T. rex could thrive in various environments, including arctic regions, due to its warm-blooded nature. This research marks a significant shift in understanding dinosaur biology, supported by years of evidence and improved methodologies.
