| 摘 要： | 北京延庆千家店地区晚侏罗世土城子组化石稀少,而新发现的恐龙足迹是北京恐龙存活过的重要证据,研究其沉积环境对恢复当时恐龙动物群的生活环境具有十分重要的意义。研究区恐龙足迹主要包括兽脚类、蜥脚类和可能的鸟脚类足迹。运用地层学、岩石学、古生物学和沉积学方法,通过地层剖面、岩石薄片、足迹分布、沉积构造及详细的粒度分布特征,综合得出千家店地区土城子组三段恐龙足迹点的沉积环境,认为当时的沉积环境为含火山碎屑的浅湖沉积,恐龙足迹的赋存层位为湖滨环境。

| Abstract: | Few fossils have been found in Late Jurassic Tuchengzi Formation from Qianjiadian District, Yanqing County, Beijing. Nevertheless, the new dinosaur footprints are important evidence of dinosaurs that once lived in Beijing. The study of its sedimentary environment is very important for reconstructing the living environment of dinosaur fauna. There are theropod, sauropod and possible ornithopod tracks in the study area. Based on stratigraphic, petrological, paleontological and sedimentary research methods, the authors used the integrated characteristics of field section, dinosaur tracks distribution, sedimentary structrue and grain size distribution to study the sedimentary environment of the third member of Tuchengzi Formation in Qianjiadian area. There was a volcaniclastic shallow lake here and the dinosaur tracks were formed in a lakeshore environment. |
