Also known as Locality 19 (Romer 1928), Locality Vb (Romer & Price 1940), S. of Fulda, Hackberry Creek, North Side Little Wichita, South Side Little Wichita, North Side of Godwin Creek, faunal Zone 2, Middle Wichita Group, Texas red-beds, redbeds
Where: Baylor County, Texas (33.7° N, 99.0° W: paleocoordinates 0.1° N, 29.6° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Petrolia Formation (Wichita Group), Artinskian (290.1 - 279.3 Ma)
• "about 450-500 feet above the Coleman Junction Limestone, and not far below the Beaverburk." 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, whose base equals the base of the Bead Mountain Formation (Tabor et al. 2002), which is in the middle of the Artinskian (Wardlaw 2005)
• group of beds-level stratigraphic resolution
Environment/lithology: terrestrial; red claystone and limestone
•
Size class: macrofossils
Collected by Cope in 1908
• Romer (1928) paper is a review of vertebrates from the Texas red-beds with previously unreported (or undetailed) localities.
