Coelospirella Community, Obotanhondi Fm., Dong Ujimqin Qi Co., Neimongol Prov. (Devonian to of China)

Where: Nei Mongol, China (45.6° N, 116.8° E: paleocoordinates 36.8° N, 47.9° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Obotanhondi Formation, Pragian to Pragian (410.8 - 393.3 Ma)

• Late Siegenian to Emsian, lowest part, second part, and fourth part of five faunal divisions of the Obotanhondi Formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; sandstone

• Disarticulated shells and sand-sized matrix consistent with normal current activity. BA 3 because of intimate association with Sinostrophia-Discomyorthis Community (which occurs in calcareous, argillaceous, medium-to fine-grained greenish sandstone).
• "sand-sized matrix"
