【摘要】 以赣州盆地梅林—茅店恐龙蛋化石产地调查为基础,通过研究化石赋存岩性、实测地层剖面等方法,明确了梅林—茅店一带27处恐龙蛋化石集中产于上白垩统赣州群周田组与龟峰群河口组、塘边组地层中,从平面上与柱状剖面上阐述了蛋化石分布特征,并结合化石出土种类、形态、数量及其赋存岩性层的特点,分析探讨了恐龙产卵与埋藏之沉积环境,为进一步研究赣州盆地恐龙繁衍之古生态环境提供实际资料。

【Abstract】 Based on the investigation of dinosaur egg fossils sites in Meilin-Maodian Ganzhou Basin, by studying the occurrence lithology of fossils and measured stratigraphic sections, the paper confirmes that the dinosaur eggfossils are concentrated in the Upper Cretaceous Zhoutian Formation of Ganzhou Group and Hekou Formation, Tangbian Formation of Guifeng Group, analyzes the distribution characteristics of egg fossils in the plane and columnar sections, and then discusses the scdimentary environment where dinosaurs laid eggs and burial environment of egg fossils combined with the characteristics of species, shape, number and lithologicmember of unearthed fossils, which provides practical data for further study of the paleoecological environment of dinosaur breeding in Ganzhou Basin.
