In July 1965, two gigantic fossilized dinosaur arms replete with menacing claws were unearthed in the remote southern Gobi desert of Mongolia. Measuring 8 feet (2.4 meters), they were the longest arms of any known bipedal creature in Earth's history.
But nearly everything else was missing, leaving experts baffled about the nature of this beast with the behemoth arms. Half a century later, the mystery has been solved.
