摘　　要：四川盆地中生代地层连续,盛产恐龙化石,而自贡更是出产恐龙化石的佼佼者。大树村青龙山作为自贡三大恐龙化石产地之一,已发现的化石数量与种类丰富。在野外系统调查的基础上,总结分析了大树村古生物化石种属特征、分布特征、赋存岩性特征,对古生物化石资源进行了评价,并提出了化石保护存在的问题及建议,为古生物化石资源的保护与开发利用提供了科学依据。The Sichuan Basin is enriched in dinosaur fossils due to its continuous Mesozoic strata,and Zigong is a leader in producing dinosaur fossils.As one of the three major dinosaur fossil sites in Zigong,Qinglong Mountain in Dashu village has been found to be rich in fossil quantity and species.Based on the field systematic investigation,the species characteristics,distribution characteristics and occurrence lithology characteristics of paleontological fossils in Dashu village were summarized and analyzed,and the existing problems and suggestions of fossil protection were suggested,which provided a scientific basis for the protection,development and utilization of paleontological fossil resources.
