Where: Xinjiang, China (41.8° N, 84.2° E: paleocoordinates 34.8° S, 106.7° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Keketiekedaban Group, Wenlock to Wenlock (433.4 - 423.0 Ma)

• Except where otherwise stated, ref. 7624 uses Lower Silurian as equivalent to Llandovery, Middle Silurian as equivalent to Wenlock, and Upper Silurian as equivalent to Ludlow plus Pridoli.
