记述了广东省南雄盆地上白垩统主田组3组恐龙行迹,由杨梅坑足迹点的足迹命名了南雄鸭嘴龙足迹(Hadrosauropodus nanxiongensis ichnosp.nov.)一新种;古市足迹点的足迹归入鸭嘴龙足迹一未定种(Hadrosauropodus isp.).这是中国鸭嘴龙足迹属的首次描述,将该足迹的分布从北美拓展至中国,并为南雄盆地存在大型的鸭嘴龙提供了新的化石证据.还整理了中国已描述的大型鸟脚类足迹:中国足迹(Sinoichnites)被定为非正式的塑模标本;扬子足印(Yanatzepus)被归入兽脚类足迹;禽龙足迹(1guanodonopus)被认为是裸名,归入禽龙足迹(Iguanodontipus);嘉荫足迹(Jiayinosauropus)增加了新材料并得以具体描述;内乡足迹(Neixiang footprint)得以重新描述.

Herein we describe three trackways that pertain to Hadrosauropodus nanxiongensis ichnosp, nov. from the Yangmeikeng track site in the Nanxiong Basin, Guangdong Province, China. The tracks occur in the Upper Cretaceous Zhutian Formation. The nearby Gushi track site preserves trackways attributable to Hadrosauropodus isp. These represent the first occurrences of hadrosaur footprints in China. These discoveries expand the known distribution of hadrosaur tracks from North America to China, and provide evidence for the existence of large hadrosaurs in the Cretaceous of the Nanxiong Basin. Other previously-described, large, ostensible omithopod track occurrences in China are discussed: Sinoichnites is represented only by an informal "plastotype," Yangtzepus is at-tributable to a theropod, and Iguanodonopus is considered a nomen nudum and its specimens attributable to Iguanodontipus. New specimens of Jiayinosauropus allow some redescription of the ichnotaxon, and the unnamed Neixiang footprint is redescribed.
