Stratigraphy
Lithology and environment
| Primary lithology: | pyritic "shale" |
| Lithology description: "...found below storm wave base in very shaly strata." | |
| Environment: | marine indet. |
| Geology comments: "...below storm wave base...bracketed by Dicoelosia osloensis-Rhinopora malmoeensis Comm., indicating same BA 5 position as this Comm. ... High pyrite content and coalified organic remains (black smears and unidentifiable flakes) make indicate a low oxygen, restrictive environment." | |
Taphonomy
Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: Substantial overlap with PBDB collections 505 and 13846, but this list contains additional taxa. Collection based on Table 22.8, which includes data from four collections. Table includes relative and absolute abundance data. | |
| Taxonomic list comments:Not all taxa listed to genus level. | |
