Stratigraphy
| Formation: | Aouinet Ouenine III | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Formation said to be "Frasnian s.l.". Top of formation contains nodular limestone with conodonts that indicate Frasnian-Famennian transition. This sample interpreted as upper Frasnian, on basis of occurrence of Uniconus livnensis and Alternatus sp. in overlying sediments. | |||||
Lithology and environment
| Primary lithology: | deformed bedding,burrows,ferruginous sandstone |
| Secondary lithology: | claystone |
| Includes fossils? | Y |
| Lithology description: Formation as a whole: "sandstone beds interbedded with siltstones and claystone levels...about 60 m thick" This sample "occurs in a ferruginous sandstone" See also geology comments. | |
| Environment: | marine indet. |
| Geology comments: "Characteristic 'flyschoid' textures with load casts, burrow casts, microripples, convolute laminations and common Bifungites reflect a deeper prodeltaic to shelf environment." | |

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.
