Also known as Locality 8 (Romer 1928), Zone 0 or Zone 1, Texas red-beds, redbeds, Putnam or Admiral Formation, Boll, Cummins
Where: Archer County, Texas (33.6° N, 98.6° W: paleocoordinates 0.7° S, 29.7° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Sakmarian to Sakmarian (293.5 - 279.3 Ma)
• Details for Faunal Zone 0 of Romer 1928: "Plummer and Moore 1921 assign the Putnam Formation to the Cisco Group- boundary is at the top of the Coleman Junction Limestone."close to the line of the Coleman Junction." Cisco Group is Pennsylvanian. Details for Zone 1: "These beds [estimated thickness of 350 feet] occupy the middle portion of the Wichita as Cummins conceived of it; but they are now seen to occupy the lower part of this group. This zone is approximately equivalent to the Admiral Formation of Plummer and Moore (1921), although no definite correlation can be made at present." Lower Permian stratigraphy for Texas was modified by Hentz (1988).
•the Putnam is Sakmarian and the Admiral Artinskian (Wardlaw 2005, Permophiles)
