 note = {A large productid brachiopod species, Gigantoproductus aurita (Bolkhovitinova, 1938), is described from the Tsuchikurazawa Limestone (upper Visean-Namurian), a large limestone block within a Permian accretionary complex of Kotaki, Itoigawa City, Niigata Prefecture, central Japan. This is the fourth described Gigantoproductus species from the Tsuchikurazawa Limestone.
