摘要
兰州—民和盆地恐龙足印化石赋存和保存的特征表明:该区早白垩世中期的构造稳定,盆地扩张时期出现的湖沼环境是恐龙足印化石形成的最佳时期和场所,形成之后的湖进序列是良好的覆盖层。
The characteristics of dinosaur footprint fossils and their horizon of occurrence in the Lanzhou—Minhe Basin, Gansu, indicate that the dwelling of dinosaurs was closely related to the Early Cretaceous sedimentary environment and tectonism. The basin extension stage and tectonic-stability stage were the optimal stages for the dwelling of dinosaur and the lacustrine-swampy environment was the optimal locus for dwelling of dinosaur. The advanced sequence of lake was a good cover for forming footprints.
