Evidence of Warm-Blooded T-Rex Metabolism
According to a report from CNET published on September 16, 2026, researchers have found evidence indicating that the Tyrannosaurus rex (T-Rex) was a warm-blooded creature capable of inhabiting the Arctic. Although the iconic dinosaur went extinct approximately 66 million years ago, new research findings continue to shed light on its biological traits and environmental adaptability.
Surviving Frigid Polar Climates
Information from CNET confirms that endothermic thermoregulation enabled T-Rex to maintain a stable internal body temperature. This physiological trait allowed the species to survive in harsh, cold climates such as polar regions, rather than being restricted to warm tropical or subtropical ecosystems. Detailed methodology regarding paleothermometry measurements and specific fossil excavation sites were not detailed in the CNET report.
