A Boreal-type brachiopod species, Waagenoconcha irginae (Stuckenberg), from the middle Permian (Wordian) of the South Kitakami Belt, Japan

Abstract

This study describes a Boreal-type brachiopod species, Waagenoconcha irginae (Stuckenberg), from the lower part of the Kamiyasse Formation (Wordian) in the Kamiyasse‒Imo area, South Kitakami Belt, northeastern Japan. The occurrence of W. irginae in the South Kitakami Belt provides additional evidence for the palaeoposition of South Kitakami in the Wordian, located near North China.
