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. Some previously reported taxa are revised.
