摘　　要：剑龙类恐龙是一类长有骨板的中-大型有甲类恐龙。其最明显的特征是从颈部到尾部沿背脊有两列直立的骨板,呈对称或交错排列。已知最早的剑龙类恐龙发现于中侏罗世的欧洲和中国,在侏罗纪末期剑龙类迅速繁衍,在全球都有分布,但随后在白垩纪早期开始消亡。中国至今所发现的剑龙类恐龙化石有几十个个体材料,发表的属种共计9属10种,分别为嘉陵龙、乌尔禾龙、芒康龙、营山龙、华阳龙、沱江龙、重庆龙、巨棘龙,将军龙。从地层分布、头部、腰带、肢骨比值和骨板几个特征来看,中国剑龙类应该有一个从华阳龙-重庆龙-巨棘龙-沱江龙-营山龙-芒康龙-乌尔禾龙的演化过程。Stegosaurus is a medium-and large-class dinosaur with bony plates,the most obvious of which is the bizarre array of der-mal plates and spines that extends along the body from the neck to the end of the tail.The earliest stegosaurus are known from the Middle Jurassic of Europe and China and they achieved a global distribution by the Late Jurassic,but subsequently waned in diversity during the Early Cretaceous.Fossils of stegosaurs in China include 9 main genera:Huayangosaurus,Tuojiangosaurus,Gigantspinosau-rus,Chungkingosaurus,Chialingosaurus,Yingshanosaurus,Monkonosaurus,Jiangjunnosaurus,Wuerhosaurus.According to the char-acteristics of head,girdle,limb ratio and bone plate,Stegosaurus of China should have an evolutionary process from Huayangosau-rus-Chungkingosaurus-Gigantspinosaurus-Tuojiangosaurus-Yingshanosaurus-Monkonosaurus-Wuerhosaurus.
