Stratigraphy
| Formation: | Mint Spring | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: The Mint Spring Formation is mostly fossiliferous sands that lie disconformably above 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 alnog the Chickasawhay River in Wayne County. Here clay clasts are numerous enough to have created 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 evidence of cross-bedding. These sands have macrofauna dominated by bivalves. | |||||

| Taxonomic list comments:list uses catagories to denote values. For example: R = rare, 1 - 9 organisms found. C = common, 10 - 99 organisms found. A = abundant 100+ organisms found.
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. | |
