Anatomical examination of animal bones found at archaeological sites can provide information that historical studies alone cannot. As related in this report, we performed morphological analyses on cattle and horse bones retrieved from Joseon-period ruins found at the Gongpyeongdong site (Seoul, South Korea). By anatomical and histological comparisons, we confirmed that the slaughter of Gongpyeongdong cattle and horses was done at a later age than is the case today. This was likely due to the fact that cattle and horses in Joseon society were raised primarily as beasts of burden and only secondarily for food; and so, the Joseon government strictly prohibited what it considered to be premature slaughter.

Objective. The prevalence of calculus is known to be variable by difference in diets or subsistence strategy between human populations. However, this situation has not been confirmed so far for hunter-gatherers and farming people in terms of history. In this study, we tried to reveal the association of diets or subsistence with calculus in different historical populations: Siberian natives, Joseon period Korean people, and Russian settlers in Siberia. Design. We examined the teeth of Siberian natives (hunter-gatherers), Russian (wheat farming) settlers, and Joseon (rice farming) people in sixteenth to nineteenth century. Age and sex were estimated using the methods of Buikstra and Ubelaker (1994). We examined specimens to detect signs of calculus formation in teeth. Calculus rates in each group were statistically compared, and the proportions of calculus by age or sex were also compared across each group. We used package R for statistical analysis. Results and Discussion. The prevalence of calculus deposition decreased in the order of Joseon people, Russian settlers, and Siberian natives. Our study proposes that the rate of calculi among farming people was evidently higher than that of hunter-gatherers in sixteenth to nineteenth century Eurasia. In all three groups, calculus prevalence became higher as age increases and was noteworthy in males. Conclusion. Current study demonstrated a significant difference of calculus formation between those groups with different diets or subsistence strategies. Higher prevalence of dental calculus was observed in agriculturalist Joseon Koreans and Russian settlers, but Siberian natives exhibited relatively lower frequency of dental calculus. The results of this study enable us to reconsider the meaning of association between subsistence strategy and calculus in different historical populations.

In the general context of rescue archaeology or in any emergency salvage operation, especially where human bones are involved that need to be cremated within a short time frame, anthropologists cannot conduct their work carefully at a university or institute lab. Thus, they have sought ever-more efficient and effective investigative protocols by which work can be conducted in cases of urgent time constraints. A recent anthropological survey conducted at a small town in South Korea (Goryeung) is thus significant. A joint team of anthropologists and dress historians performed collaborative research work in a "field lab" set up at the excavation site. Our novel protocol, by which academic data demonstrably can be successfully secured in the field instead of having to be sent to a university or institute lab, could be useful for the purposes of rescue archaeology.
