OMNH V1005 (Carboniferous of the United States)

Where: Seminole County, Oklahoma (34.9° N, 96.7° W: paleocoordinates 5.0° S, 30.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Ada Formation, Virgilian (303.7 - 298.9 Ma)

• from a "single stratigraphic horizon... 22.4 m above the contact" with the "underlying Vamoosa Formation"

• bed-level stratigraphic resolution

Environment/lithology: coarse channel fill; gray mudstone

• bone horizon is from "tributary channel fill deposits" immediately below a layer of "pedogenic carbonate nodules"

Size class: macrofossils

Collection methods: quarrying, surface (float), sieve,

• All of the in situ specimens recovered from the locality were found within a single stratigraphic horizon stretching approximately 11 m along the face of the outcrop. Screenwashing of 40 kg of sediment recovered "very little additional material"
