T.Rex's puny arms were not useless at all; they served an unexpected and brutal purpose

Paleontologists debate the purpose of Tyrannosaurus rex's famously small arms. One theory suggests these limbs were used for close-range slashing attacks on prey. These arms possessed curved talons and a wide range of motion for inflicting wounds. Other researchers propose the arms were for courtship displays rather than hunting. Ultimately, the jaws likely remained the primary weapon for the massive dinosaur.
