Tooth study indicates Tyrannosaurus rex was warm-blooded

--> In the United States, an analysis of the enamel of three Tyrannosaurus rex teeth found in Montana showed that this dinosaur’s body temperature was approximately 36.3°C. This indicates that it was warm-blooded, Cyprus Mail reports.

Scientists estimated the body temperature of Tyrannosaurus rex at 97.3°F, or 36.3°C, with a margin of error of 2.5°C. By comparison, the average human body temperature is 37°C. The figure is also close to that of an elephant — around 36°C — but lower than that of an ostrich, which is approximately 39°C.

Senior study author Aradhna Tripati, a geologist at the University of California, Los Angeles, noted that an animal with a body temperature of around 36°C did not depend on solar heat to warm itself. According to her, in terms of thermoregulation, Tyrannosaurus rex was closer to an elephant or an ostrich than to a crocodile.
