Tushibulage Formation at Qiaerqiake Mountain, Lop Nur, E Xinjiang Province (Silurian of China)

Where: Xinjiang, China (41.0° N, 90.0° E: paleocoordinates 33.6° S, 116.4° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Tushibulage Formation, Llandovery (443.4 - 433.4 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.

• formation-level stratigraphic resolution
