Where: Allen County, Louisiana (30.0° N, 92.0° W: paleocoordinates 31.6° N, 81.0° W)

When: 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
