Also known as Field no. NF93LA-28

Where: Red River Parish County, Louisiana (32.0° N, 93.4° W)

• Paleocoordinates: 38.0° N, 64.5° W (Wright 2013)

• coordinate stated in text

• hand sample-level geographic resolution

When: Dolet Hills Formation (Wilcox Group), Paleocene (66.0 - 56.0 Ma)

• Late Midwayan Age, middle Paleocene.

•20-30 cm above top of 6-cm-thick flaser-bedded hard siltstone bed, whose base is 3.4 m above top of unit OC-2A.

Environment/lithology: terrestrial; gray mudstone and fine-grained, gray sandstone

Size class: microfossils

Preservation: original sporopollenin

Collection methods: bulk, chemical, hydrochloric, hydroflouric

• Two sets of slides were made for all samples. One set was made from residues that were not sieved after the original samples had been broken down using HNO3 (lignites) or HCl and HF (detrital rocks). The other set of slides was made from residues that had been sieved to retain the size fraction larger than 8 µm.
