摘　　要：中国江苏省东海县南古寨孟疃组发现了数种恐龙足迹,包括兽脚类足迹和蜥脚类足迹。这些足迹出现在同一层位的四个相邻的足迹化石点。这些足迹化石点至少保存了三种不同形态的兽脚类足迹和未成年—成年的蜥脚类足迹。南古寨三号足迹化石点的兽脚类足迹和蜥脚类足迹出现了"回填"现象,这是在足迹所附带的沉积物与基底地面相互作用下,产生的流体和塑性行为下形成的。Diverse dinosaur （theropod and sauropod） tracks from the Nanguzhai track locality in Donghai County,Jiangsu Province,China occur in the Lower Cretaceous Mengtuan Formation. The locality is subdivided into four adjacent track sites at the same stratigraphic level. The sites preserve at least three track types pertaining to theropods to juvenile-adult sauropods. ＂Backfilled＂ theropod and sauropod tracks at Nanguzhai Site III are the products of appendage-sediment interactions where the substrate was fluid and behaved plastically.
