摘要：A new record of hadrosaur , Jiayinosauropus johnsoni ichnogen. et ichnosp. nov. , was established on the basis of a well preserved footprint . The specimen was collected from the Yong’ancun Formation of Jiayin Group of early Late Cretaceous. The site is situated on the right bank of the Heilongjiang River , near Jiayin County , Heilongjiang Province. It was a pedal impression of a hadrosaur. It appeared a broadly tridactyl foot and possessed wide and thick digital . There are webs
between the digits.
    The first hadrosaur , Mandschurosaurus amurensis (Riabinin , 1925 ,1930) , was reported on the south bank of Heilongjiang River. It showed that the duck-bill dinosaurs existed in the region during the Cretaceous age. This footprint , Jiayinosauropus , is the first record of hadrosaur footprint in China.
