摘　　要：以虎、狮、棕熊、黑熊等13种动物的肱骨为研究对象,观察了肱骨形态特征,并测量了有关参数。结果发现,食肉动物肱骨与草食动物存在明显差别。不同种类动物肱骨的差别呈现一定的规律性。肱骨的形态特征与动物活动方式存在一定的相关性。进行肱骨分类比较时,肱骨后天活动形成的部分形态特征应谨慎使用。该研究将为动物骨骼的分类或鉴别提供一定的启示。The humerus of 13 species of mammals were used as the research objects to observe the morphological characteristics and measure the related parameters.The results showed that there were obvious differences of humerus between carnivorous and herbivorous animals.The difference of humerus among different species of animals showed a certain regularity.There was a certain relationship between the morphological characteristics of humerus and the activity ways of animals.When comparing the classification of humerus,some morphological features generated by the activity of humerus should be used with cautions.This study would provide some inspirations for the classification or identification of mammal’s bones.
