Stratigraphy
Formation:Saelabonn
Stratigraphic resolution:member
Stratigraphy comments: Upper parts of formation. Type locality is in Limovnstangen Mbr.
Lithology and environment
Primary lithology:shelly/skeletal "limestone"
Secondary lithology:hummocky CS calcareous siltstone
Includes fossils?Y
Lithology description: "...most of the fauna found in thin to thick bioclastic beds interbedded with shale and calcareous siltstone. There are numerous sedimentary structures, among others hummocky cross lamination in the lower parts of the sequence."
Environment:marine indet.
Geology comments: "...Hummocky CS [indicates] transition zone into lower shoreface. Thereafter there is an upwards shallowing, which may have led to deosition into the supralittoral zone. Deposition mainly within shoreface, very shallow. Shelf strongly affected by storms and tidal influence secondary. [Based on relation to previous fauna, community is in] BA 2."
