Qidong Section, upper part, Qidong County, Hunan (Devonian of China)

Where: Hunan, China (26.8° N, 112.1° E: paleocoordinates 3.8° S, 105.9° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Early/Lower Famennian (376.1 - 370.6 Ma)

• Measured section is about 20m. The lower fauna comes from about 3m to 5m. The upper is from a few levels between 13m and 20m. The two faunas correspond roughly to lower and upper crepida zones, i.e. to Yunnanellina and Yunnanella brachiopod zones.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; marl and shale

• [limestone from 0m to about 13m, then a shale bed , then marl to the top]
