Geography
| Country: | Armenia |
| Coordinates: | 39.9° North, 44.9° East (view map) |
| Paleocoordinates: | 8.2° South, 41.1° East |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | small collection |
Time
| Period: | Permian | Epoch: | Guadalupian |
| Stage: | Wordian | 10 m.y. bin: | Permian 4 |
| Key time interval: | Wordian | ||
| Age range of interval: | 266.90000 - 264.28000 m.y. ago |
Stratigraphy
| Formation: | Arpa | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Basal unit of the Midian stage of the Tethyan timescale. Kotlyar et al. (1989) identified two fusulinid zones, the lower Yangchienia thompsoni and the upper Chusenella abichi. In central Iran, Chusenella abichi occurs with Neoschwagerina margaritae (Leven, 1998), suggesting a Wordian age for the entire Arpa Formation. | |||||
