Stratigraphy
Lithology and environment
| Primary lithology: | calcareous "shale" |
| Includes fossils? | Y |
| Lithology description: "Calcareous shale." | |
| Environment: | marine indet. |
| Geology comments: "Environment: BA 2 if occurring only with abundant Cloudella or possibly BA 3 if with a more diverse community slightly lower in the sequence."
SEP: environmental call here is impossible without additional information and I have not found a good source yet | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: May be a subset of Collection number 593 (Dalhousie Shale), but that collection does not include Cloudella, which is said here to be locally abundant. | |
| Taxonomic list comments:Not all higher taxa listed to genus level. | |
