Where: Hubei, China (30.7° N, 111.3° E: paleocoordinates 3.3° N, 127.2° E)
• coordinate based on political unit
• local area-level geographic resolution
When: Shiwuzi 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. Shiwuzi formation used by authors to refer to what has been the lower (or lower and middle) part of the Shamao formation. Late Llandovery age based on graptolites; correlation chart shows Telychian age.
• formation-level stratigraphic resolution
Environment/lithology: marine; green, yellow shale and siltstone
