Where: Allen County, Louisiana (30.0° N, 92.0° W)
• Paleocoordinates: 34.5° N, 72.7° W (Wright 2013)
• small collection-level geographic resolution
When: Wilcox Group, Eocene (56.0 - 33.9 Ma)
• Horizon sample from drill core. 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.
• bed-level stratigraphic resolution
Environment/lithology: deltaic; siltstone and shale
Size class: microfossils
Preservation: original chitin, original sporopollenin
Collection methods: core, chemical,
Primary reference: W. A. Gregory and G. F. Hart. 1995. Distribution of pollen and spores in a subsurface marine Wilcox (Paleocene-Eocene) section in southwest Louisiana. Palynology 19:1-43 [R. Lupia/R. Vaughn]more details
Purpose of describing collection: paleoecologic analysis
