| Formation: | Ely Limestone |
| Stratigraphic resolution: | bed |
Lithology and environment
| Primary lithology: | lithified packstone |
| Lithology description: "packstone" from strat colum (fig. 2) | |
| Environment: | shallow subtidal indet. |
Taphonomy
| Modes of preservation: | body,replaced with silica |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | some macrofossils |
| Collection methods: | bulk,mechanical,acetic,field collection |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: "Slabs were disolved using acetic acid to remove carbonate and some residual minerap phases, leaving silicified fossil associations of brachiopods although carbonate brachiopod specimens were also found and removed using mechanical procedures"
echinoderms were reported present on strat column (Fig. 2) but were not in faunal list | |
