Bled Douarah- Upper Faunal Level, upper subunit (Miocene of Tunisia)

Also known as Bled el Douarah, yellow sands

Where: Gafsa, Tunisia (34.0° N, 8.0° E: paleocoordinates 33.8° N, 7.7° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Beglia Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• Beglia Formation is divided into units. Two fossiliferous levels have been identified. The Upper Faunal Level is subdivided into two units- upper and lower subunits. The age of the formation is estimated to be 12.5-9.5 Ma. No more specific dating is available, however Hipparion is present in both subunits of the Upper Faunal Level.

• bed-level stratigraphic resolution

Environment/lithology: lacustrine; poorly lithified, yellow, conglomeratic sandstone

• Fossils collected from several localities, thought to be approximately the same age. Localities in the upper subunit of the Upper Faunal Level are 2,4,6,9,14, 16, and 28.
• Units 13 is a yellow sand, cross-laminated with lateral lenses of coarse conglomerate with mudballs.

Size classes: macrofossils, mesofossils

Collection methods: bulk, surface (float), surface (in situ),

• Information on stratigraphic level is only available for some taxa.
