Where: Libya (26.0° N, 10.5° E: paleocoordinates 48.0° S, 27.4° E)
• coordinate based on political unit
• local area-level geographic resolution
When: Talagrouna Formation, Late/Upper Frasnian (379.5 - 376.1 Ma)
• Formation rests unconformably on Lower Silurian rocks. Dated as Late Frasnian on basis of tentaculites.
• formation-level stratigraphic resolution
Environment/lithology: marine; siltstone and sandstone
Collection methods: Emphasis of monograph is brachiopods and bivalves. Other elements sometimes mentioned as well. I am combining elements that are said to belong to two distinct assemblages (there is also a "mixed" assemblage). It is not clear to what extent the assemblages are stratigraphically distinct.
