Stratigraphy
| Formation: | Aouinet Ouenine II | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Formation said to be "Givetian s.l. and basal Frasnian". Samples in upper part of formation. | |||||
Lithology and environment
| Primary lithology: | siltstone |
| Secondary lithology: | sandstone |
| Lithology description: Formation as a whole: "shales, siltstones, and sandstones, with several layers enriched by ferruginous matrix. The sandstone levels...are richly fossiliferous". | |
| Environment: | marine indet. |
| Geology comments: "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" | |
Taphonomy
Collection methods and comments
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: Focus of monograph is brachiopods and bivalves, but other elements are sometimes mentioned in passing.
