Stratigraphy
Stratigraphy comments: Probably Late Llandoverian or Early Wenlockian. Lowermost part of Semenov Regional Stage, underlying Jolvia multiplexa community. |
Lithology and environment
Primary lithology: | ferruginous "limestone" |
Includes fossils? | Y |
Lithology description: "Occurs in massive, tough, ferruginous limestone in the lowermost part of the Semenov Regional Stage" | |
Environment: | marine indet. |
Geology comments: Lithology and morphology of shells (pedicle; heavy ventral valves) suggest level bottom conditions, whereas ration of articulated to disarticulated shells suggests quiet water. BA 3. Elsewhere related Pentameridae and Trimerella commonly found in rough water. |
