Septoparmella Community, Lingshan, Guangxi Province (Devonian of China)

Where: Guangxi, China (22.4° N, 109.3° E: paleocoordinates 5.8° N, 125.3° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

• "The unpublished South China occurrence, from an unnamed formation, is assigned to the Gedinnian because of the presence of Septoparmella."

• formation-level stratigraphic resolution

Environment/lithology: marine; calcareous mudstone

• "low-diversity, high-dominance, low-density community...Presumably it represents deep-water, relatively quiet water, BA 4-5 [based on comparison with similar communities elsewhere]"
• "scattered, disarticulated valves in a calcareous mudstone matrix"
