Where: Sichuan, China (34.0° N, 103.0° E: paleocoordinates 37.1° S, 126.0° E)

• coordinate estimated from map

• basin-level geographic resolution

When: Pailungchiang Formation, 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. Ref. 7624 refers to Pailungchiang as formation, whereas previous working groups called it a group. Collection is from upper subgroup (subformation). Sichuan Working Group dated this part of formation as Middle-Upper Silurian; ref. 7624 assigns to Ludlow, but that call is based on material from different locality.

• formation-level stratigraphic resolution

Environment/lithology: marine; sandy slate and limestone

Collection methods: Material studied by the Working Group of the Regional Stratigraphic Chart of Sichuan (1974).
