Lithology and environment
| Primary lithology: | volcaniclastic calcareous "shale" |
| Secondary lithology: | "limestone" |
| Lithology description: "The lithology is distinguished by tuffaceous and calcareous shales with intercalations of fine-grained volcanoclastic rocks and locally developed thin impure limestone beds. The facies is close to the Aulacopleura Shale but the representation of trilobites is different; complete exoskeletons are found in distinct layers." | |
| Environment: | marine indet. |
| Geology comments: "Sediments...border the volcanic elevations seawards from those with the Bumastus-Sphaerexochus-Cheirurus Assemblage; generally a lower energy BA 4-5..This assemblage, however, is contained in an impoverished form even in tuffaceous beds penetrating far offshore from the volcanic elevations into...graptolite shale facies..." | |

Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| Taxonomic list comments:Only trilobites are listed to genus level, but many other groups reported present. Moreover, not all trilobites are listed. | |
