Gongpoquansaurus (meaning "Gongpoquan reptile") is an extinct genus of basal hadrosauroid dinosaur that was not formally named until 2014, while the name was a nomen nudum for many years previously. It is known from IVPP V.11333, a partial skull and postcranial skeleton. It was collected in 1992 at locality IVPP 9208–21, from the Albian Zhonggou Formation ( Xinminpu Group), in Mazongshan, Gansu Province, China. The specimen was first described and named by Lü Junchang in 1997 as the third species of Probactrosaurus, Probactrosaurus mazongshanensis.^[2] Following its description, several studies found it to be less derived than the type species of Probactrosaurus in relation to Hadrosauridae. Therefore, "Gongpoquansaurus" had been suggested, yet informally, as a replacement generic name.^[1] In 2014, the species was formally redescribed, and the describers erected Gongpoquansaurus.^[1]
