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.A new record of hadrosaur, Jiayinosauropus johnsoni ichnogen. et ichnosp. nov., was established on the basis of a well preserved footprint.
