【摘要】 本文通过对78件胡氏贵州龙标本的特征性状进行分析与测量,并对选定的10组特征性状比率关系进行统计分析,认为胡氏贵州龙在生长发育过程中头、眼、肱骨、股骨与身体其他部分有明显的异速生长特征,并根据这些特征将胡氏贵州龙的个体发育分为:胚胎期,幼年期,少年期,青年期及成年期五个阶段。除胚胎期外各个阶段的特征明显,可以通过定量的方法加以区别。更多还原

【Abstract】 In this paper,by analysis 78 specimens of Keichousaurus hui,with 10 ratios of measurements if morphological characteristics,some beneficial conclusions are obtained.The result shows that allometric growth of Keichousaurus Hui can be seen between its skull,eyes,humerus,femurs with other body portions.By using this characteristic,the ontogenesis of Keichousaurus Hui can be divided into five stages: embryo,infancy,adolescenece,subadult and adult.Except embryo,other stages are well distinguished by using quantitative methods.更多还原
