Ethiopian amber (IGR collection) (Miocene of Ethiopia)

Where: Ethiopia (10.1° N, 39.1° E: paleocoordinates 8.8° N, 37.4° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Early/Lower Miocene (23.0 - 16.0 Ma)

• 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.

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; lithified amber

Size classes: macrofossils, mesofossils

Preservation: soft parts, amber

Collection methods: Repository: Geological Department and Museum of the Université de Rennes (IGR)
