Tooth Chemistry Suggests T. Rex Was Warm-Blooded, With Human-Like Body Temperature
A new tooth-based study is adding weight to the long-running scientific view that Tyrannosaurus rex was not a cold-blooded reptile, but an active, internally regulated predator with a body temperature closer to that of modern mammals. The findings sharpen a broader debate over dinosaur metabolism and could help scientists better understand how giant animals adapted to changing climates and ecosystems.
