Where: Sichuan, China (32.1° N, 104.6° E: paleocoordinates 4.0° N, 133.6° E)
• coordinate based on political unit
• local area-level geographic resolution
When: "Pailungchiang" Group, Wenlock to Wenlock (433.4 - 419.2 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. Ref. 7624 does not accept this as Pailungchiang s.s. Age span of "Pailungchiang Group" in correlation chart is Upper Llandovery to Pridoli; I infer that the middle and upper parts would be post-Llandovery.
• group-level stratigraphic resolution
Environment/lithology: marine; phyllite and argillaceous limestone
