(Geology)}, month = {Mar}, note = {In this paper, we describe an early Carboniferous (early Visean) brachiopod fauna (the Odairayama fauna) from the middle part of the Arisu Formation in the Yokota area, South Kitakami Belt, northeastern Japan. The Odairayama fauna consists of six species in six genera: Tomiproductus elegantulus, Marginatia burlingtonensis, Rhipidomella michelini, Cleiothyridina harkeri, Kitakamithyris hikoroitiensis and Asyrinxia nipponotrigonalis. The age of the fauna is assigned to early Visean. Therefore, the middle part of the Arisu Formation is correlated with the lower Visean.}, pages = {9--25}, title = {Early Carboniferous (early Visean) brachiopod fauna from the middle part of the Arisu Formation in the Yokota area, South Kitakami Belt, Japan}, volume = {34}, year = {2019} }
