DAILY PRESS. NEWS. T. Rex, King of the Dinosaurs, Had a Body Temperature of 97 Degrees Hotter than a crocodile, cooler than a chicken, T. Rex was definitely warm-blooded, according to a new study. The last vestiges of warmth drained out of a Tyrannosaurus rex’s body around 66 million years ago, but scientists just used chemistry to take the long-extinct dinosaur’s temperature: 97 degrees, give or take a few. The new finding securely situates the king of the dinosaurs among the warm-blooded animals, confirming previous years of research. T. rex ran hot, but not too hot, according to the study, published Wednesday in Science Advances. Instead, the reading places it somewhere on the body-temperature spectrum near large mammals like Indian elephants (97 degrees) or humans (98 degrees) or flightless birds like ostriches (101 to 103 degrees) — but nowhere near the heat of a chicken, say (105 to 107 degrees). “That is absolutely spectacular,” said Jasmina Wiemann, a molecular paleobiologist at Johns Hopkins, who was not involved in the study. Up until the early 2000s, dinosaurs were thought to be rather reptilian and therefore probably coldblooded, Dr. Wiemann said. That began to change as multiple lines of evidence from geochemistry studies and CT scans of fossils showed they were warm-blooded. Dr. Wiemann had previously found that T. rex had a fast metabolism, but she said the new study did an “exquisite” job of zeroing in on a precise body temperature.
