The fearsome T Rex dinosaur used its small arms to viciously slash its prey, according to scientists who showed that the prehistoric carnivore's front limbs were far from useless. For more than a century, many paleontologists have viewed the small arms of T rex as having been vestigial. Scientists from the University of Hawaii in the US showed that the arms' were adapted for slashing preys at close quarters. The arm bones were quite robust and would readily have sustained the impact of slashing, researchers said. Tyrannosaur ancestors used long arms primarily for grasping.
