Stratigraphy
| Formation: | Tupelo Bay | Member: | Pregnall | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Powell & Baum used Cross at formation rank, but that usage is not followed in later publications. According to Edwards et al. (1997), the Cross Member of the Santee Limestone is dated as both late middle Eocene and late Eocene, representing calcareous nannofossil Zones NP 17 and NP 18. Geisler et al. (2005) re-assessed the stratigraphy and named the Tupelo Bay Formation to include the type Cross Member/Formation and coarser-grained units, which belong to the earliest Priabonian (NP18) Pregnall Member. It is not clear which unit is exposed at the Santee Quarry, but the invertebrate fauna is extremely similar to the Pregnall Member at the Giant Portland Quarry. | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal lithified packstone |
| Includes fossils? | Y |
| Lithology description: the upper eocene cross formation is composed of molluscan biomicrudites which grade updip into molluscan biosparrudites. | |
| Environment: | open shallow subtidal |
| Geology comments: Coarse grain size, dominance of packstone and grainstone, and abundance of broken shells suggests shallow subtidal environment | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | all microfossils,difficult macrofossils |
| Reason for describing collection: | biostratigraphic analysis |
