Stratigraphy
| Formation: | Mint Spring | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: The Mint Spring Formation consists of fossiliferous sands that lie disconformably above the estuarine clays of the Forest Hill Formation. The sands of the Mint Spring Formation are moderately clean and often show cross-bedding. These sands indicate a near-shore shelf environment and have macrofauna dominated by bivalves. | |||||

| Includes fossils? | Y | ||
| Environment: | offshore | Tectonic setting: | passive margin |
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:list uses catagories. For example: R = rare, 1 - 9 valves collected. C = common, 10 - 99 valves collected. A = abundant, 100+ valves collected.
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. | |
