Stratigraphy
| Formation: | Red Bluff | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: Red Bluff formation is exposed in Clark and Wayne counties, Mississippi. It consists of fossiliferous, dark grey, silty clay with zones of ironstone concentrations in lower part.These sediments conformably overlie the blue-grey, blocky, marine clay of the Shubuta Clay Member of the Yazoo Formation and were deposited in shallow marine shelf, prodelta, and marginal delta bay enviroments. Lower part of the Red Bluff Formation is the most fossiliferous. Otoliths are also abundant here. | |||||

Taphonomy
| Modes of preservation: | body,original aragonite,original calcite |
| Size of fossils: | mesofossils |
Collection methods and comments
| Collection excludes: | all microfossils,some macrofossils,difficult macrofossils |
| Collection methods: | bulk,mechanical,field collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: bivalves only | |
| Taxonomic list comments:Because author denoted all species that he found more than 99 individuals as abundant or "A", I've used a similar system on the taxonomic list. 1- 9 individuals rare (R), 10 -99 (C) common, and 99+ (A) abundant like the author had before. Categories are listed in the comments field, absolute abundances are given in the abundance field.
Since taxa with greater than 99 specimens were not counted with absolute abundances, these were reported with category "A" for abundant. | |
