Stratigraphy
| Stratigraphy comments: nilssoni-scanicus zones |
Lithology and environment
| Primary lithology: | sandstone |
| Lithology description: "...occurs in decalcified sandstones within basinal graptolite sequences..." | |
| Environment: | marine indet. |
| Geology comments: "Probably BA 5...no graptolites apparently associated in the trilobite-bearing sandstones, adn there is therefore a possibility that the shelly fossils are allochthonous. However, faunas of this composition are not found higher on the paleoslope." | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Reason for describing collection: | paleoecologic analysis |
