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.

Environment/lithology: marine; limestone and shale

• Correlation chart indicates BA 3 position.
• "The lower part of the group consists of limestone, shale, and sandstone, having a thickness of 2069 m. In the limestone Heliolites and Favosites have been found, but the base of the group is covered. Lateral to the lower part of this section a shelly fauna includes [list]."
