Gobihadros was a small, plant-eating dinosaur that lived in what is now Mongolia. It had a beak like a duck and could walk on two legs or all fours. Scientists found a nearly complete skeleton, so we know a lot about its body.1

Gobihadros is the first non-hadrosaurid hadrosauroid from the Late Cretaceous of central Asia known from a complete, articulated skull and skeleton.1

It had up to three functional teeth in each tooth position in its lower jaw, which is unusual for a hadrosauroid.1

The upper jaw of Gobihadros had a 'double-layer' oral margin, a feature also seen in later hadrosaurids.1

Its ilium (hip bone) had a sigmoidal (S-shaped) upper outline and a fan-shaped rear process, which helped scientists identify it as a new species.1

Gobihadros had a spike-like thumb claw on its hand, which it may have used for defense or digging.1

The fossils were collected by a joint Mongolian-Japanese expedition between 1993 and 2004.1
