T-rex's Useless Hands! | #dinosaurs #trex #interestingfacts #dinosaur #paleontology #dinomachine

The Tyrannosaurus rex is revered as one of the most fearsome creatures to inhabit the earth, with an average weight of six tons and the power to tear off 500 pounds using its massive jaw. But one researcher believes the dinosaur’s most ridiculed body part may have been just as vicious: the T. rex’s puny, undersized arms.
According to Steven Stanley, a paleontologist at the University of Hawaii at Manoa, T. rex arms were used to slash prey in close proximity to the dinosaur. The arms, which were approximately three feet long, featured crescent-shaped talons that could be used to inflict mortal wounds to prey. And the short arm length was actually more beneficial for slashing, considering the size of T. rex’s head.
“Its short, strong forelimbs and large claws would have permitted T. rex, whether mounted on a victim’s back or grasping it with its jaws, to inflict four gashes a meter or more long and several centimeters deep within a few seconds,” Stanley reported at a Geological Society of America meeting in October 2017. “And it could have repeated this multiple times in rapid succession.”
In the past, T. rex arms had been believed to be nothing more than holdovers after years of the predator’s evolution, like wisdom teeth for humans or wings for flightless birds. But several factors led Stanley to conclude that the arms of the premier predator of the prehistoric era may have potentially been useful.
