摘　　要：文章系统地对中国恐龙蛋化石的地理分布作了总结，并将恐龙蛋化石类型归纳为９科，１３属，２１种。在此基础上，着重分析了恐龙蛋化石古生态特征，分别从蛋化石的排列方式，恐龙产蛋的方式，不同类型蛋化石间及蛋化石与骨骼化石共生几方面作了探讨。The dinosaur egg fossils recognized in China are characterized by widespread occurrence in stratigraphic horizons,diverse types and well preserved original morphology:in places,they are found to be associated with the skeletal remains and other fossils.The geographic distribution of these egg fossils is herein outlined.Twenty one species,thirteen genera and nine families heve been distinguished.The approaches focus on palaeoecological features and arrangement of the egg fossils,ways of laying eggs and paragenetic relationships between various types of dinosaur egg fossils and between the egg fossils and skeletal remains.Finally the direct indicator significance of the dinosaur egg fossils in the division and correlation of the Late Cretaceous strata is also explored in this paper.
