名字的意思： “hadrosauroid from the Gobi Desert of Mongolia”1

吃：植物有喙的草食恐龍白堊紀晚期

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

酷東西

趣味知識

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

發現: Gobihadros was named in 2019 by Khishigjav Tsogtbaatar, David B. Weishampel, David C. Evans, and Mahito Watabe. The type specimen, a nearly complete skeleton, was found at Bayshin Tsav in the Gobi Desert, Mongolia.4 1
