Lithology and environment
| Primary lithology: | shelly/skeletal,gray calcareous packstone | ||
| Lithology description: biohermal complex with eight distinct facies ranging from crinoidal grainstones to fissile shales and including wackestones, packestones, and mudstone; corals predominantly from well bedded, light gray to blue, coral-rich, crinoidal packstones with distinct coral-rich fissile shale interbeds | |||
| Environment: | reef, buildup or bioherm | Tectonic setting: | foreland basin |
Taphonomy
| Modes of preservation: | body,original calcite,replaced with silica |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | some macrofossils,difficult macrofossils |
| Collection methods: | mechanical,field collection,observed (not collected) |
| Reason for describing collection: | biostratigraphic analysis |
| Taxonomic list comments:corals were the most predominant fauna and thus identified to a generic level, other fauna listed in broad taxonomic categories | |
