Where: Sichuan, China (34.0° N, 103.0° E: paleocoordinates 37.6° S, 124.5° E)
• coordinate estimated from map
• local area-level geographic resolution
When: Pailungchiang Formation, Ludlow (427.4 - 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. Ref. 7624 refers to Pailungchiang as formation, whereas previous working groups called it a group. "the fauna suggests an Upper silurian age. In this region, because this unit is restricted to the Upper Silurian, we prefer formational to group status."
• member-level stratigraphic resolution
Environment/lithology: marine; gray sandstone and limestone
