Stratigraphy
| Formation: | Steinvika Limestone | Member: | Skavraker |
| Stratigraphic resolution: | member |
Lithology and environment
| Primary lithology: | bioturbation lithified argillaceous lime mudstone |
| Secondary lithology: | "shale" |
| Lithology description: At Skavråker the lowermost 3.6 m of the member consist of pale calcilutites with subordinate argillaceous mudstones. The latter occur as thin, wispy, and discontinuous laminae and impart a reticulate aspect to the pale calcilutites. The mudstone is highly bioturbated. | |
| Environment: | deep subtidal shelf |
| Geology comments: Interbedded thinly laminated bioclastic calcilutites and argillaceous mudstones | |
Taphonomy
| Modes of preservation: | body,cast |
| Size of fossils: | macrofossils |
Collection methods and comments
| Reason for describing collection: | biostratigraphic analysis |
