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

Also known as Bled ed Douarah, yellow sands, upper level

Where: Gafsa, Tunisia (34.0° N, 8.0° E: paleocoordinates 33.7° N, 7.5° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Beglia Formation, Serravallian to Serravallian (13.8 - 7.2 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.

•Mannaï-Tayech 2009: underlying Beglia sands were dated Serravallian to Lower Tortonian, based on their vertebrate faunal contents (Robinson and Black, 1974; Mannaï-Tayech and Otéro, 2005).

• bed-level stratigraphic resolution

Environment/lithology: lacustrine; poorly lithified, yellow, argillaceous, 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 3, 5, 12, 15, and 27.
• Yellow, cross-laminated sands, many clay beds 5-15 cm thick.

Size classes: macrofossils, mesofossils

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

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