Stratigraphy
| Geological group: | Wilcox | ||||
| Stratigraphy comments: Gregory and Hart (1995a, pollen and spores) do not recognize the Clairbornian in the core, but in Gregory and Hart (1995, dinoflagellates), they do. Both papers look at the same samples from the same core and derive different age assignments because they treat each independently. RAL elected to enter a uniform age assignment for both papers. | |||||
Lithology and environment
| Lithology description: ""50 siltstones and shale samples"" - individual sample lithology not specified | |||
| Environment: | deltaic indet. | Tectonic setting: | passive margin |
| Geology comments: Although the authors discuss prodelta and delta front as depositional environments, they do not specify explicitly which they choose. The most specific correct entry is thus selected here. | |||
Taphonomy
| Modes of preservation: | original chitin,original sporopollenin |
| Size of fossils: | microfossils |
Collection methods and comments
| Collection methods: | core,chemical |
| Reason for describing collection: | paleoecologic analysis |
