Geography
| Country: | China | State/province: | Guangxi | County: | Nandan |
| Coordinates: | 24.5° North, 115.6° East (view map) | ||||
| Paleocoordinates: | 2.3° South, 114.9° East | ||||
| Basis of coordinate: | based on political unit | ||||
| Geographic resolution: | local area |
Time
| Period: | Devonian | Epoch: | Middle Devonian |
| Stage: | Eifelian | 10 m.y. bin: | Devonian 3 |
| Key time interval: | Eifelian | ||
| Age range of interval: | 393.30000 - 387.70000 m.y. ago |
Stratigraphy
| Formation: | Nandan | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: "Abundant specimens of Nowakia sulcata, and rare goniatites, provide the age information for this Nandan Formation community." | |||||
Lithology and environment
| Primary lithology: | mudstone |
| Lithology description: "brachiopods occur as very scattered, chiefly disarticulated, small specimens. The beds consist of dark-colored, thin-bedded (about 0.5 cm) mudstone." | |
| Environment: | marine indet. |
| Geology comments: "The Nowakia and goniatites are pelagic, and the trilobites may be epibenthic as these beds have not yielded trilobite trace fossils. We interpret these strata as BA 4-5, relatively quiet water, lower oxygen." | |
