1880-III-B-2/2, Bir al Qasr Fmn., Ash Shati area, N. flank of Murzuk Basin (Devonian of Libya)

Where: Libya (27.6° N, 12.6° E: paleocoordinates 53.7° S, 41.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Bi'r al Qasr Formation, Eifelian (393.3 - 387.7 Ma)

• Age range of formation is Eifelian to Givetian (ref. 8780). However, the bulk is Eifelian, and the Givetian age applies only to the uppermost beds.

• bed-level stratigraphic resolution

Environment/lithology: marine; sandstone and silty claystone

• Formation in general: "In the typical development, the Formation begins with med-gr. sst, continues w/ silty clayst. b eing interbedded w/ sst., and is finished with sst." [ref. 8780]

Collection methods: Listed by ref. 9606 as 1880-III-3/2, but, based on ref. 8780, I think this is a misprint for 1880-III-B-2/2
