| Abstract: | The Dinosaurs'' footmark fossils in the Lanzhou-Minhe Basin appear either at the top of regressive cycles or at the base of transgressive cycles and vary greatly in different horizons and parts. The morphology of the Dinosaurs'' footmark fossils is believed to be closely related to sedimentary environments. The littoral environments during the basin opening phases may be most favourable for the preservation of the Dinosaurs'' footmark fossils. |
