Paleontologists unearthed the fossil in Mongolia’s Gobi Desert, and the find is unique because of a sheath preserved on one of the digits, which reveals the claw’s true length.

While Duonychus tsogtbaatari had formidable claws, they were likely used to grasp vegetation, according to a study of a fully preserved fossil from the Gobi Desert.

Scientists have discovered a new species of dinosaur in Mongolia's Gobi Desert. Called Duonychus tsogtbaatari, the dinosaur has two foot-long clawed fingers on each hand, one fewer than its fellow therizinosauria.
