Awaynat Wanin type sect., Aouinet Ouenine II Fmn., samples SM203-SM209 & RB319 (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". Samples from about 1/3 of the way up from base of formation.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; sandstone

• Both articulated and disarticulated shells with some fragmentation. Interpreted as substantially affected by waves/currents. "BA 2; wholly marine, shallow subtidal with quiet to normal current activity"
• Formation as a whole: "shales, siltstones, and sandstones, with several layers enriched by ferruginous matrix. The sandstone levels...are richly fossiliferous". These samples are from sandstones. Sample SM208 described as fine-grained and quartzose.

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