Abstract :This paper describes a Permian brachiopod fauna (Ishinazaka fauna) from shale and argillaceous limestone boulders in the basal conglomerate of the Pliocene Kume Formation of Hitachi, central Japan, and reexamines the age and palaeobiogeography of the fauna. The results, which are the same as our previous opinions, are as follows: 1) the Ishinazaka fauna, consisting of 17 species in 16 genera, resembles the middle Permian brachiopod fauna of the South Kitakami Belt in species composition, and indicates a middle Permian (Wordian) in age; 2) the Ishinazaka fauna is a mixed Boreal‒Tethyan fauna in the Sino-Mongolian‒Japanese Province; and 3) the Hitachi area was probably part of the continental shelf bordering the eastern margin of North China during the Wordian.
