Our new paper is out in Archaeology, Ethnology and Anthropology of Eurasia, official journal of Russian Academy of Science (Siberian Branch)-.
This article presents the results of experiments aimed at testing the hypothesis that the mummification of human bodies in Joseon Dynasty burials was caused by an exothermic reaction and the consequent destruction of intestinal flora. Well-preserved mummies of that period were discovered only in the Hoegwakmyo tombs, where the lime-soil mixture barrier was present. Experiments were conducted using animals’ bodies placed in miniature grave models. Immediately after contact with moisture, the temperature inside the coffin surrounded by a lime-soil-mixture increased to 130.8±23.5°C and remained stable for 141.0±64.7 minutes. The examination of bacterial cultures on Mac Conkey or blood agar plates showed that the entire flora normally existing in the rat’s intestine was completely sterilized by high temperature. We also demonstrate that the same mummification can be reproduced regardless of the sizes of miniature graves.

Our paper, " Ancient mitochondrial DNA analysis of avian bones collected from the 4th century pit burial found in South Korea " is published in Archaeological Research in Asia. Pheasant is a bird commonly interred in the ancient graves of Korea. The avian bones collected during excavation are sometimes too small to be used for morphological species identification. Since ancient DNA (aDNA) analysis becomes widely used nowadays for molecular diagnosis, we carried out aDNA research on the 4th century avian femurs (K-14 and K-15) for which the species could not be confirmed by conventional zooarchaeological technique. In this study, we revealed that the mitotypes of the current ancient specimens were almost identical to those of modern genus Phasianus DNAs reported in NCBI/GenBank, re-confirming the usefulness of the genetic analysis on genus Phasianus bones when the species identification of the ancient avian bones found at archaeological sites is in a dispute.
