Awaynat Wanin type sect., Aouinet Ouenine II Fmn., sample SM217 (Devonian to of Libya)

Where: Libya (28.1° N, 13.0° E: paleocoordinates 47.0° S, 32.5° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Aouinet Ouenine II Formation, Givetian to Givetian (387.7 - 372.2 Ma)

• Formation said to be "Givetian s.l. and basal Frasnian". Samples in upper part of formation.

• bed-level stratigraphic resolution

Environment/lithology: marine; siltstone and sandstone

• "Shells always disarticulated, oriented parallel with bedding, but a higher degree of fragmentation is uncommon. The environment was slightly turbulent, and indicates a shallow subtidal regime"
• Formation as a whole: "shales, siltstones, and sandstones, with several layers enriched by ferruginous matrix. The sandstone levels...are richly fossiliferous".

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