Lithology and environment
| Primary lithology: | pyritic poorly lithified "shale" |
| Secondary lithology: | lithified siltstone |
| Lithology description: Greenish-gray to bluish-gray shales with some pyrite interbedded with discontinuous siltstones | |
| Environment: | offshore shelf |
Taphonomy
| Modes of preservation: | body |
| Degree of concentration: | -single event |
| Size of fossils: | macrofossils |
| Spatial orientation: | life position |
| Articulated whole bodies: | some |
| Size sorting: | poor |
| Fragmentation: | occasional |
| Temporal resolution: | snapshot |
| Spatial resolution: | autochthonous |
Collection methods and comments
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: Collection only includes brachiopods and bivalves, but text says brachiopods are "most abundant...with bivalves as a minor constituent of the total fauna" and formation is generally "sparsely fossiliferous" | |
