Maopinggou (Silurian of China)

Where: Shaanxi, China (33.1° N, 109.2° E: paleocoordinates 3.4° N, 130.3° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Monoclimacis griestoniensis graptolite zone, Upper Member (Wangjiawan Formation), Telychian (438.5 - 433.4 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.

• member-level stratigraphic resolution

Environment/lithology: marine; shale and limestone

• Correlation chart indicates ba5 based on graptolitic fauna.
• "The formation has a total thickness of 257.3 m, and includes abundant shale and siltstone, with minor amounts of limestone (including a basal limestone which weathers to a honeycomb-like surface)."
