Abstract

This study describes a brachiopod fauna, consisting of 15 species in 15 genera, from the lower part of the Takakurayama Formation at the locality T1 in the Takakurayama area, Abukuma Mountains, South Kitakami Belt, northeastern Japan. The fauna is considered to be late Permian (Wuchiapingian) in age based on the occurrence of Haydenella wenganensis, Costatumulus tazawai and Pterospirifer alatus. In terms of palaeobiogeography, the Takakurayama (T1) fauna is a mixed Boreal—Tethyan fauna with Chonetinella, Lamnimargus, Megousia, Costalumulus, Yakovlevia, Neospirifer, Gypospirifer, Alispiriferella and Pterospirifer as the Boreal (anti-tropical) elements, and Haydenella, Transennatia and Echinauris as the Tethyan (tropical) elements. The fauna is allied with the middle—late Permian brachiopod fauna of South Primorye, Far Eastern Russia.
