Geography
| Country: | Ethiopia |
| Coordinates: | 10.1° North, 39.1° East (view map) |
| Paleocoordinates: | 8.8° North, 37.4° East |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | local area |
Time
| Period: | Neogene | Epoch: | Miocene |
| 10 m.y. bin: | Cenozoic 5 | ||
| Key time interval: | Early Miocene | ||
| Age range of interval: | 23.03 - 15.98 m.y. ago |
Stratigraphy
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Originally assigned a Late Cenomanian age, but early Miocene according to conference abstract by Perrichot et al. (2018). Coty et al. argue for Cenozoic age as well. There is a Cenozoic sandstone intercalated between Quaternary and late Miocene basalts. As the amber is purchased, the exact stratigraphic horizon is uncertain. Amber maturity and fossil content suggests young Cenozoic age. | |||||
