 note = {A brachiopod fauna (the Onimaru fauna), consisting of six species in five genera, is described from the Onimaru Formation in the Nagaiwa?Onimaru area, South Kitakami Belt, northeastern Japan. The age of the fauna is identified as the late Visean. Palaeobiogeographically, the Onimaru fauna has a close affinity with the lower Carboniferous faunas of southwestern Japan (Akiyoshi Belt), northern Russia (northern Urals), England, Kazakhstan and northwestern China (Xinjiang and Qinghai). The South Kitakami region was probably the eastern extension of the North China Province, and located near and to the east of the North China Block in the late Visean.},
