【 摘 要 】

References(18)Cited-By(6)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. In badgers, 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.
