摘要
以于都盆地恐龙蛋化石产地调查为基础,通过研究化石赋存岩性和实测地层剖面特征,明确了恐龙蛋化石集中产于晚白垩世周田组,从平面与柱状剖面上阐述了恐龙蛋化石分布特征,并结合化石出土种类、形态、数量及其赋存岩性段等特点,分析探讨了恐龙产卵滨湖-浅湖相沉积环境以及恐龙蛋化石原地-准原地埋藏环境,为进一步研究周田期盆地演化规律、古环境提供实际资料。
Based on the investigation of dinosaur egg fossils sites in Yudu Basin,by studying the occurrence lithology of fossils and measured stratigraphic sections,the paper confirmes that the dinosaur egg fossils are concentrated in the Late Cretaceous Zhoutian Formation,analyzes the distribution characteristics of egg fossils in the plane and columnar sections,and then discusses the lakeside-shallow lake facies sedimentary environment where dinosaurs laid eggs and autochthonous-parautochthonous burial environment of egg fossils combined with the characteristics of species,shape,number and lithologic member of unearthed fossils,which provides actual data for further study of evolution law and paleoenvironment of basins.
