Middle Permian fusulinoideans from Hatahoko in the Nyukawa area, Gifu Prefecture, Mino Belt, central Japan

A Middle Permian fusulinoidean fauna composed of 12 species in 10 genera, including Cancellina nipponica (Ozawa), Neoschwagerina cf. simplex Ozawa, Neofusulinella praecursor Deprat, N. cf. giraudi Deprat, etc., is described from Hatahoko in the Nyukawa area, east of Takayama, Gifu Prefecture, central Japan. The limestone containing this fauna is one of exotic limestone blocks with paleo-equatorial Panthalassan seamount origin in the Jurassic accretionary complexes of the Mino Belt, southwest Japan. Judging from the cooccurrence of C. nipponica and N. cf. simplex, the Hatahoko fauna is coeval with that reported from the upper part of the conventional Cancellina nipponica Zone (Nn) or the Neoschwagerina simplex to the Pseudodoliolina ozawai Zones of the Akasaka Limestone in the southern part of Gifu Prefecture, which is another world-famous limestone body with abundant fusulinoidean remains in the Mino Belt, and is referable to the early Murgabian (early Wordian)
