Braggs-Pine Barren-Bed 14 (Paleocene of the United States)

Where: Lowndes County, Alabama (32.1° N, 86.8° W)

• Paleocoordinates: 37.0° N, 56.1° W (Wright 2013)

• coordinate stated in text

• outcrop-level geographic resolution

When: Pine Barren Member (Clayton Formation), Danian (66.0 - 61.6 Ma)

• The Clayton Formation disconformably overlies the Prairie Bluff Formation.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; unlithified, silty sandstone

• Bed 14 is unlithified sandy silt. 4m thick. At Braggs there are numerous lithologies including limestones, marls, coarse transgressive lags and glauconitic sands.

Size class: mesofossils

Collection methods: bulk, surface (in situ),

• Some areas were sampled on the outcrop surface, others were excavated with pick and shovel and some more specimens came from screenwashing bulk sediments. Collection efforts were focused on the basal Clayton Formation.
