Aduogabu section, sample 3 (Permian of China)

Where: Xizang, China (31.6° N, 84.6° E: paleocoordinates 15.6° S, 64.0° E)

• coordinate stated in text

• outcrop-level geographic resolution

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

• In conclusion, 10 of 17 species generally suggest Lopingian age except for four indeterminate species. Notably, Spinomarginifera chengyaoyenensis with a Changhsingian age accounts for approximately half of the total quantity of brachiopods. Therefore, this fauna can be assigned to the Changhsingian age based on the brachiopods and their co-occurring foraminifers Colaniella parva (Colani, 1924) and Reichelina pulchra Miklukho-Maklay, 1954.

• bed-level stratigraphic resolution

Environment/lithology: lithified limestone

Size class: macrofossils

Reposited in the NIGPAS
