Awaynat Wanin type sect., Aouinet Ouenine II Fmn., sample UB179 (Devonian of Libya)

Where: Libya (28.1° N, 13.0° E: paleocoordinates 49.9° S, 36.5° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Aouinet Ouenine II Formation, Givetian (387.7 - 382.7 Ma)

• Formation said to be "Givetian s.l. and basal Frasnian". Sample is from near base of formation.

• bed-level stratigraphic resolution

Environment/lithology: marine; sandstone and siltstone

• "Shells badly preserved, but several...with closed shells indicate low intensity of current activity"
• Formation as a whole: "shales, siltstones, and sandstones, with several layers enriched by ferruginous matrix. The sandstone levels...are richly fossiliferous" For this sample: "Fossils occur in thin ferruginous intercalations in a sequence of interbedded sandstones and siltstones"

Collection methods: Focus of monograph is brachiopods and bivalves, but other elements are sometimes mentioned in passing.
