First Member of the Paradise Formation (Carboniferous of the United States)

Where: Cochise County, Arizona (31.9° N, 109.2° W: paleocoordinates 7.0° S, 47.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Paradise Formation, Carboniferous (358.9 - 298.9 Ma)

• definitely either St. Louis or Ste. Genevieve but "tentatively correlated with the St. Louis"

• member-level stratigraphic resolution

Environment/lithology: gray limestone and calcareous shale

• "The 79 feet of beds of the First member are about equally divided between medium-bedded gray limestone and poorly exposed shale with thin beds of limestone"

Size class: macrofossils

Preservation: original calcite
