Abstract：A large scale of dinosaur footprints, which were related to the dinosaur movements in a shore-shallow lake environment under hot drought climate of the Dasheng Group of the late Early Cretaceous were discovered in Linshu area，Shandong Province. In the research area，sauropod footprints were dominant, as well as a small number of ornithopod footprints，ropod footprints and the ankylosaur-like footprints. The ankylosaur footprints were very scarce in China.The main directions of these footprints were west and southwest.Based on the features of ornithopod and sauropod tracks, we can conclude that these dinosaurs were in a slowly walking state, especially the ornithopod. The discovery of the footprints in the research area suggested that the vertebrate animals such as dinosaurs(including birds)were survival in China and even in East Asia in the late Early Cretaceous， which had great significance to reveal the terrestrial biotas evolution in the Late Mesozoic. Footprints preservation has a close relationship with the different sedimentary environment by comparing with the dinosaur footprints fossil in the strata of the late Early Cretaceous.Therefore, research on dinosaur footprints can provide much more information for recovering palaeoecology and palaeogeographic environment.
