Research Abstract
In this project, we aimed at clarifying the relationship between diet, habitat, and microscopic use wear on the teeth of large herbivorous mammals and then reconstructed the diet of extinct species and animals excavated from archaeological sites. The analysis of the extant species (sika deer, Japanese serow, Japanese macaque, and wild boar) with known diets showed that, in ruminants, as the consumption of grasses increases, deep scratches are formed on the tooth surfaces more frequently and the surface becomes more rugged due to the abrasion effect of phytoliths in the grasses. In omnivorous species, on the other hand, the tooth surfaces became flat when foraging on fibrous plants, whereas the rougher surfaces resulted from foraging on hard objects such as seeds. These relationships allowed quantitative dietary reconstructions of fossil species.
