Where: Allen County, Louisiana (30.0° N, 92.0° W: paleocoordinates 31.6° N, 81.0° W)
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
Size class: microfossils
Preservation: original chitin, original sporopollenin
Collection methods: core, chemical
