Lithology and environment

| Environment: | transition zone/lower shoreface | Tectonic setting: | passive margin |
Taphonomy

| Size of fossils: | mesofossils |
Collection methods and comments
| Collection excludes: | all microfossils,some macrofossils |
| Collection methods: | bulk,mechanical,field collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: bivalves only | |
| Taxonomic list comments:bivalves only**abundances are given as counts ONLY for those species with fewer than 100 specimens - for 100 or more, he just gives "A" for "abundant". In the case where a collection includes an "A", we enter abundance classes for species instead of counts as follows: Fewer than 10 specimens = R (rare)10 to 99 specimens = C (common)Greater than 99 specimens(Dockery's "A") = A (abundant)In this reference, "specimens" equals "valves" | |
