• coordinate based on nearby landmark
• local area-level geographic resolution
When: Belle Plains Formation (Wichita Group), Artinskian (290.1 - 279.3 Ma)
• Details for Faunal Zone 2 of Romer 1928: "Beyond the horizon of Godwin Creek is found a series of beds about 200 feet in thickness, of a transitional character, in which thin and impure limestones are occasionally present."
•the base of the Artinskian is just above Coleman Junction Formation (Wardlaw 2005, Permophiles), and the "Belle Plains" = Petrolia Formation is below the Waggoner Ranch Formation, which is well above the Coleman Junction and whose base equals the base of the Bead Mountain Formation (Tabor et al. 2002), which is in the middle of the Artinskian (Wardlaw 2005)
