Stratigraphy
| Formation: | Mint Spring | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: The Mint Spring Formation consists of fossiliferous sands that lie disconformably above the estuarine clays and sands of the Forest Hill Formation. This contact is characterized by shell gravels that are largely comprised of the bivalve "Callista", by lithified clay clasts bored by the bivalve "Jouannetia", and by shark and ray teeth. Lithified clay clasts are especially common at the base of the Mint Spring Formation along the Chickasawhay River in Wayne County. Here clay clasts are numerous enough to form a cobble bottom on the Mint Spring sea floor. These clasts formed a hard substrate utilized by a variety of encrusting organisms. The sands of the Mint Spring Formation are moderately clean and often show cross-bedding. These sands indicate a near-shore shelf enviroment 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:the taxonomic list uses catigories to describe the abundances of the valves. 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. | |
