The arms were small, but the answer is not.

For more than a century, those tiny forelimbs have fueled jokes, cartoons, and serious scientific debate alike. How could one of the most formidable predators to ever walk the planet end up with proportions that seem almost impractical? The mismatch between massive skull and miniature arms has long felt like evolution’s punchline. But fossils do not preserve accidents, they preserve patterns. And recently, researchers began looking at those patterns differently. What they uncovered does not make the T. Rex look awkward. It makes it look intentional in ways most people never considered.
