Late Devonian rhynchonellids (Brachiopoda) from the Junggar Basin, northwestern Xinjiang

Rhynchonellid brachiopods from the Late Devonian (broadly late Frasnian-Famennian) Hongguleleng Formation in the Junggar Basin, northwestern Xinjiang, consist of 12 species (six not identified to species-level) in 11 genera. Three new species are established with the aid of serial sections: Sinotectirostrum triangularum, Evanescirostrum gracilis and Megalopterorhynchus boulongourensis.
