AWi-2, Catherine-Thomaston Highway (Paleocene of the United States)

Where: Wilcox County, Alabama (32.2° N, 87.5° W: paleocoordinates 35.2° N, 67.4° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

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

• Clayton spans most of Danian, including nanofossil zones NP1, NP2, and NP3; foram zones P1a and P1c (absence of P1b attributed to ecological factors rather than a hiatus, by Schulte & Speijer, 2009).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithology not reported

• Clayton primarily represents littoral (foreshore) and inner and middle neritic (offshore transition zone). The majority of the thickness likely represents offshore transition, with some shoreface settings, but with no stratigraphic or lithologic information this collection cannot be assigned an environment.
• Much of the formation is composed of calcareous sandstones, but also marls and sandy packstones.

Size class: mesofossils
