Tuvaella gigantea Comm., Ludlow, Barkol County, Xinjiang Province (Silurian of China)

Where: Xinjiang, China (43.8° N, 93.5° E: paleocoordinates 38.9° N, 20.7° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Ludlow (427.4 - 423.0 Ma)

Environment/lithology: marine; argillaceous sandstone

• "The disarticulated nature of the shells, except for Meristina, and the occurrence in a fine- to medium-grained argillaceous sandstone, suggest a moderate amount of current movement. The overall aspect of the fauna suggests BA 3." [After some discussion, authors infer that community occurs in BA 2 and 3.]
• "fine- to medium-grained argillaceous sandstone"
