An occurrence of a stegodont molar from Seiryukutsu-Cave in Hiraodai Karst Plateau is reported. The material, anterior three crests of 3DM, represents characteristics of molars of Stegodon orientalis Owen. It shows a presence of late Early Pleistocene deposits in this area. The molar is almost unworn with slight occlusal facets at the anterior two crests, and it indicates very young stage of the individual.
