oks1 (Carboniferous to of the United States)

Also known as ETE Locality 2, Capital Coal Co., USNM 38362, oks1,

Where: Mcintosh County, Oklahoma (35.5° N, 95.5° W: paleocoordinates 6.8° S, 31.1° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Boggy Formation (Krebs Group), Westphalian D to Westphalian D (311.4 - 307.0 Ma)

• The Secor Coal Member is in the Boggy Formation of the Krebs Group in Oklahoma.

• group of beds-level stratigraphic resolution

Environment/lithology: crevasse splay; gray, silty mudstone

• The sediments probably represent a rapidly prograding delta lobe; plants growing on the prograding deltaic silts and muds were preserved as compression fossils in crevasse-splay sediments.
• Carbonized compression fossils were collected from light to medium gray, silty mudstones between the Secor and Secor Rider coals.

Size class: macrofossils

Preservation: adpression

Reposited in the USNM

Collection methods: surface (float),
