To obtain the data required for identification of skeletal remains excavated from archaeological sites, histometrical observations were made in the cross sections of the mid-shaft of humerus, radius, femur and tibia of raccoon dogs (Nyctereutes procyonoides) and badgers (Meles meles) captured in Kagoshima Prefecture. There were interspecific differences between both animals in the breadth, the depth and the area of medullary cavity at the mid-shaft of the bones, all measurements were greater in male than in female bones. The thickness and the area of compact bones in male raccoon dogs were larger than those of female. No differences in histological structure could be detected among the bones, but an interspecific difference was found in the shape of osteons; round and constant-sized osteons consisting of 3 to 5 lamellae in raccoon dogs, while round or elliptic osteons varying in size from 3 to 8 lamellae in badgers. The ratios, the osteon areas per unit compact bone areas, were higher in all the bones of raccoon dogs. The short diameters of osteons and the ratios were greater in males in both animals. In females, the short diameter of osteons was smaller, and the number of osteons was larger. The results revealed interspecific differences between both animals and sexual dimorphism in each species.
为获取用于鉴定从考古遗址发掘出的骨骼遗骸所需的数据，对在鹿儿岛县捕获的貉（Nyctereutes procyonoides）和獾（Meles meles）的肱骨、桡骨、股骨和胫骨骨干中段横截面进行了组织计量学观察。两种动物在骨骼骨干中段髓腔的宽度、深度和面积方面存在种间差异，所有测量值雄性骨骼均大于雌性骨骼。雄性貉致密骨的厚度和面积大于雌性。各骨骼之间未检测到组织学结构差异，但在骨单位形状上发现了种间差异；貉的骨单位呈圆形且大小恒定，由3至5层骨板组成，而獾的骨单位呈圆形或椭圆形，大小从3至8层骨板不等。骨单位面积与单位致密骨面积的比值在貉的所有骨骼中都更高。两种动物中雄性的骨单位短径和比值都更大。在雌性中，骨单位短径较小，骨单位数量较多。结果揭示了两种动物之间的种间差异以及每个物种的两性异形。
