重庆綦江莲花保寨保存有大量以莲花卡利尔足迹为主的恐龙足迹,研究其沉积环境对恢复当时恐龙动物群的生活环境有着十分重要的意义。运用岩石学、沉积学和古生物学方法,通过岩石学特征、沉积构造特征、粒度分布特征等分析重庆綦江莲花保寨恐龙足迹群的沉积环境,认为当时的沉积环境为曲流河沉积,恐龙足迹的赋存层位为曲流河边滩和河漫滩环境。 There are a lot of dinosaurs in Chongqing Qudai lotus preserved in the lotus Kalilian footprints. It is of great significance to study the sedimentary environment for restoring the living environment of dinosaur fauna at that time. Using the methods of petrology, sedimentology and paleontology, the sedimentary environment of the dinosaur footprints in Lianhuabaizhai of Qiongjiang in Chongqing was analyzed by petrological characteristics, sedimentary structural features and grain size distribution characteristics. The sedimentary environment at that time was considered as meandering river sediments, dinosaur footprints The occurrence of layers of meandering riverside beach and river floodplain environment.
