Abstract
A Carboniferous spiriferid brachiopod Purdonella tschernyschewiformis (Ozaki, 1931) was collected from a piece of limestone float, derived from the Upper Carboniferous (Bashkirian) limestone of the Ichinotani Formation in the Mizuboradani Valley, Fukuji area, Hida Gaien Belt, central Japan. Purdonella has mainly been reported from the Upper Carboniferous and Lower Permian of the Boreal region, and P. tschernyschewiformis has been described from the Upper Carboniferous (Bashikirian-Moscovian) of Northeast China (Liaoning) and Northwest China (Xinjiang). Therefore, the occurrence of P. tschernyschewiformis from the Upper Carboniferous limestone of Fukuji indicates that the Hida Gaien region, including the Fukuji area, was part of the continental shelf along the eastern margin of North China (Sino-Korea) during the Late Carboniferous.
