Researchers analyze how heat would move through a Tyrannosaurus rex’s body and estimate that the dinosaur likely ran significantly hot—hotter than some earlier models suggested. The work links body temperature to the amount of food the animal would need to sustain its metabolism.

The findings imply that T. rex had a high energy requirement, making it consistent with a lifestyle as an active predator and/or a scavenger. Both outlets describe the same overall conclusion: a warmer body temperature would have supported an energetically demanding way of life.

While the sources agree on the estimated heat level and its metabolic implications, they differ in what they emphasize. ABC News focuses on what the temperature means for diet and behavior, while the other listing provides limited additional detail beyond the headline. Across coverage, the central theme is that heat-balance modeling suggests T. rex was a high-metabolism animal rather than a cooler, slower-moving one.
