Small-sized cyrtospiriferids from the Upper Devonian (late Frasnian) of Central Hunan, China
The late Frasnian brachiopods of central Hunan of south China were predominated by an atrypid-rhynchonellid-cyrtospiriferid assemblage. The cyrtospiriferid brachiopods are characterized by abundant small-sized forms which comprise four species belonging to at least three genera. Two new species (Cyrtospirifer? variabilis and Mennespirifer yangqiaoensis) are described.
