中国山东省诸城盆地张祝河湾村下白垩统杨家庄组发现了非鸟恐龙(蜥脚类和鸟脚类)与古鸟类足迹。该足迹点的非鸟恐龙足迹深受水浸沉积物的影响,发生了强烈变形。蜥脚类足迹的前后足迹面积相近,造迹者行进缓慢。鸟脚类足迹属于禽龙-鸭嘴龙类型的足迹。古鸟类足迹并不类似于中国以往发现的中生代鸟类足迹,而类似于韩国滨水鸟类足迹的金东鸟足迹(Jin-dongornipes)。讨论了莱阳足迹(Laiyangpus)和拟跷脚龙足迹(Paragrallator,亦译为拟似鹬龙足迹),前者因模式标本遗失而不明确,后者可归入安琪龙足迹未定种(Anchisauripus isp)。这批足迹的发现大大增加了山东省东部恐龙的多样性。
Non-bird dinosaurs (sauropods and ornithogs) and ancient bird trails were found in the Lower Cretaceous Yangjiazhuang Formation of Zhangzhuhewan Village, Zhucheng Bay, Zhucheng Basin, Shandong Province, China. The non-bird dinosaur footprint at this footprint was strongly affected by flooding sediments and was strongly deformed. Sauropod footprints before and after the footprints of the area are similar, making progress slow. Bird feet footprints belong to the Iguanodon - a type of footblood footprint. The ancient bird tracks are not similar to the Mesozoic bird tracks previously discovered in China, but are similar to the Jin-dongornipes of South Korea’s waterfront bird tracks. The Laiyangpus and Paragrallator are also discussed. The former is ambiguous because of missing model specimens. The latter can be classified as Anchisauripus isp. . The discovery of these footprints has greatly increased the diversity of dinosaurs in eastern Shandong Province.
