Schech-Abd-el-Ourun, Thebes (Eocene of Egypt)

Also known as Sheikh Abd el-Qurna

Where: Egypt (25.4° N, 32.4° E: paleocoordinates 15.5° N, 27.0° E)

• coordinate estimated from map

When: Esna Formation, Ypresian (56.0 - 47.8 Ma)

• From the "Cinquième Etage" of Delanoue, according to Oppenheim. Stenzel (1935) and Miller (1947) attributed the specimen to the Esneh Shale (now called Esna Formation). Lowest member of Esna Formation is Thanetian, but upper three are Ypresian age.

Environment/lithology: offshore; lithified shale

• Described primarily as deep middle shelf pelagic shale to outer shelf pelagic shale by El-Azabi & Farouk (2011), suggesting offshore environment.

Size class: macrofossils

Preservation: replaced with pyrite, replaced with limonite

Collected by Blanckenhorn, Schweinfurth in 1902-1903; reposited in the BSP, TMM

• Some material sent by Oppenheim to H. B. Stenzel (BEG specimens at University of Texas)
