Birket Qarun 2 (Eocene of Egypt)

Also known as BK-2; BQ-2; BQ 2; Birket Qarun Locality 2

Where: Egypt (29.6° N, 30.6° E: paleocoordinates 24.9° N, 26.5° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Umm Rigl Member (Birket Qarun Formation), Priabonian (37.2 - 33.9 Ma)

• "183 m below the contact of the Qasr el Sagha and Jebel Qatrani formations... This horizon was recently placed in the lowermost (Umm Rigl) Member of the Qasr el Sagha Formation, but renewed work indicates that these fossiliferous alluvial sediments are lithologically distinctive and best retained in the Birket Qarun Formation"; according to Seiffert et al. 2005 the fossilferous beds are "229 m below Quarry L-41," "about 5 to 15 cm thick," and based on new paleomagnetic data within C17n.1n and "earliest Priabonian"

• group of beds-level stratigraphic resolution

Environment/lithology: "channel"; ferruginous, shelly/skeletal sandstone

• "alluvial" (Seiffert et al. 2003) or "deposited by meandering streams... clearly fluvial" and "close to the coast" (Gunnell et al. 2008)
• "bioclastic ironstone conglomerate" (Seiffert et al. 2003) or "ironstone-rich fining upward sequences of medium-to-fine grained sands and muds"

Size classes: macrofossils, mesofossils

Collected by E. R. Seiffert, E. L. Simons

Collection methods: bulk, quarrying, sieve,

• fossils" recovered either by dry-sieving of loose sediment or by quarrying," and according to Seiffert et al. 2005, collections were made in 2001 through 2003

•CGM collection
