Gyanyima Section, unit 1, Zanda County (Permian of China)

Also known as Reef 4112

Where: Xizang, China (30.7° N, 80.7° E: paleocoordinates 48.0° S, 61.1° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Gyanyima Formation, Changhsingian (254.2 - 252.2 Ma)

• Well-preserved rugose corals are accompanied by a highly diversified foraminiferal fauna that includes Reichelina cribroseptata Erk, 1941, Reichelina changhsingensis Sheng and Zhang, 1958, Colaniella fusiformis Song, 1990, Colaniella parva (Colani, 1924), and others. These foraminiferids indicate a possible Changhsingian (late Permian) age (Wang et al., 2010).
