Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | some macrofossils |
| Collection methods: | field collection |
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: Specimens from this site are split into an informal zonation. The zonation utilizes both acme and occurrence zonules, and subdivides some zonules into numbered subunits based on clearly distinguishable assemblages. However, relative species abundances, although reflected to some extent in the biostratigraphic zonation, are not listed. Only trilobites are included in the faunal list. The zonule name will be listed in the Zone datafield. | |
