An international team of paleontologists and Earth scientists has identified fossilized remains as a two-clawed therizinosaur. The fossils were unearthed more than a decade ago in Mongolia. Their paper is published in the journal iScience.

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.

A new species of dinosaur named Duonychus tsogtbaatari has been discovered by scientists, and unlike other therizinosaurs, this species has only two clawed fingers instead of three.
