Section Ma2, Turkey Creek (Devonian of the United States)

Where: Marshall County, Oklahoma (34.2° N, 96.9° W: paleocoordinates 36.7° S, 53.6° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Turkey Creek Formation, Pragian (410.8 - 407.6 Ma)

• 5 feet of limestone

• group of beds-level stratigraphic resolution

Environment/lithology: lithified, shelly/skeletal, gray packstone

• Most of the brachiopod shells are articulated, pointing to a moderate energy level. The position of the Turkey Creek sediments with respect to an ancient strandline cannot be determined on the basis of this single, small outcrop.
• Light-gray skeletal limestone, dominantly a pelmatozoan sparite.

Size class: macrofossils
