Stratigraphy
Formation:Talagrouna
Stratigraphic resolution:formation
Stratigraphy comments: Formation rests unconformably on Lower Silurian rocks. Dated as Late Frasnian on basis of tentaculites.
Lithology and environment
Primary lithology: siltstone

Lithology description: "a 20-25 m thick sequence of siltstones interbedded with quartzose sandstones"
Environment:marine indet.
Taphonomy
Collection methods and comments
Reason for describing collection:paleoecologic analysis
Collection method comments: 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.
