We might finally now know why T. rex had such tiny arms

Recent studies suggest that the tiny arms of the T. rex might have been an evolutionary adaptation to help the massive dinosaur maintain balance and agility while hunting. Researchers propose that the small forelimbs could have also played a role in mating displays or as a vestigial trait from their ancestors. This insight sheds light on the complex behaviors and physical adaptations of these apex predators, offering a deeper understanding of dinosaur evolution and how they dominated their ecosystems.
