Where: Oklahoma (34.4° N, 96.5° W: paleocoordinates 31.2° S, 57.4° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Hunton Group, Pridoli to Pridoli (423.0 - 410.8 Ma)

• "Lower Devonian (Gedinnian). Lower Haragan Formation and Cravatt Member, Bois d'Arc Formation."

Environment/lithology: deep subtidal ramp; argillaceous, silty wackestone and micaceous, argillaceous, cherty/siliceous wackestone

• "An outer BA 4 to inner 5 (most likely the latter) position is probable"

•SEP environmental call based on given information and knowledge of local strat

• "The Haragan is a thin-bedded muddy to silty calcareous wackestone (marlstone) that weathers to form glades with a rubble of calcareous nodules and losse fossils. The Cravatt Member..is similar but more calcareous and often variabley cherty...In both units fossils are commonly concentrated into thin horizons or lenses, only very rarely showing size sorthing or winnowing...holdfasts common..."

Size class: macrofossils
