Where: Yunnan, China (25.5° N, 103.8° E: paleocoordinates 9.1° N, 129.9° E)
• coordinate based on political unit
• local area-level geographic resolution
When: Kuanti 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. Chen Jun-yuan et al. (1981) extended formation into the Wenlockian, but fossils suggest Ludlow age.
• formation-level stratigraphic resolution
Environment/lithology: marine; argillaceous siltstone and shale
