a stratified habitation site in Hoeryong District, Hamgyong-Pukto Province, Democratic People’s Republic of Korea. Dating from the late Neolithic to the early Iron Age, O-Dong was excavated between 1950 and 1954. Dozens of pit houses and outbuildings were investigated. The pit houses were arranged in four rows and were rounded or rectangular, with hearths that were simply hollow depressions or made of stone.
Two types of Neolithic complexes are distinguished in O-Dong. One is characterized by obsidian artifacts and painted pottery—gray or coated with engobe. The other complex is characterized by large polished stone implements and pottery with comb-shaped ornamentation. The finds included the bones of domestic swine and grains of scarlet runner, millet, and foxtail millet.
