Where: Nei Mongol, China (45.5° N, 117.0° E: paleocoordinates 32.7° N, 46.8° E)
• coordinate estimated from map
• local area-level geographic resolution
When: Llandovery to Llandovery (443.4 - 427.4 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. "Working Group...of Nei Monggol...placed these rocks in the Llandovery-Wenlock, but without studying the collections we can suggest nothing more than a probable Silurian age." Fossils from middle part of sequence.
• group-level stratigraphic resolution
Environment/lithology: marine; green, yellow, argillaceous siltstone and argillaceous sandstone
