Ragley Lumber #D1 well - 10809ft (Eocene of the United States)

Where: Allen County, Louisiana (30.0° N, 92.0° W)

• Paleocoordinates: 34.5° N, 72.7° W (Wright 2013)

When: Wilcox Group, Eocene (56.0 - 33.9 Ma)

• 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.

Environment/lithology: deltaic

• 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.
• ""50 siltstones and shale samples"" - individual sample lithology not specified

Size class: microfossils

Preservation: original chitin, original sporopollenin

Collection methods: core, chemical

• Author uses 'r' to denote 'single occurrence' and 's' to denote '1

Purpose of describing collection: paleoecologic analysis

Taxonomic list

• Some species names are excluded (particularly for gymnosperms) for many of the taxa listed. Abundance data good, but requires marine palynomorph info from Gregory and Hart (1995b) to complete counts.
