ATLANTA – Scientists have suspected for almost 60 years that Tyrannosaurus rex was warm-blooded. When a fossilized T. rex footprint turned up in Alaska in 2022, it added to evidence that these predators could thrive in frigid environments, where most cold-blooded reptiles could not. Now, researchers have put a figure on the temperature that tyrannosaurs … Read more
