摘要: 皖南齐云山地区恐龙骨骼化石、恐龙蛋化石、恐龙足迹和尾迹化石“三位一体”，为世界罕见。描述了三大类５属７种（或未定种）恐龙化石的形态、大小、结构特点，分析了化石在地层划分方面的意义。按化石产出层位，皖南有恐龙活动的时间约为４０００万年。
Abstract: The “trinitarian” occurrence of dinosaurian skeleton, eggs and footprints and tailprints in the Qiyunshan area, southern Anhui, is rare in the world. This paper describes the morphologies, sizes and structures of five genera and seven species （or indeterminate species） of three major classes of dinosaurs and analyzes the significance of these fossils in stratigraphic division. According to the horizon of the fossils, the age of activity of dinosaurs in southern Anhui is considered to be about 40 Ma B.P.
