Military Trail, 32 (Waggoner Ranch Formation) (Permian to of the United States)

Also known as Locality 32 (Romer 1928), faunal Zone 3, Upper Wichita Group, Texas red-beds, redbeds

Where: Baylor County, Texas (33.8° N, 99.1° W: paleocoordinates 1.5° N, 29.0° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Waggoner Ranch Formation (Wichita Group), Artinskian to Artinskian (290.1 - 272.3 Ma)

• Details for Faunal Zone 3 of Romer 1928: "approximately 230 feet in thickness...The total thickness of the Wichita group, as thus defined is, in this region, approximately 780 feet." Clyde Formation is approx. equivalent to Waggoner Ranch Formation (Hetz and Brown 1987).

•the Waggoner Ranch Formation is equivalent to the Bead Mountain through Lueders formations (Tabor et al. 2002), which are late Artinskian and early Kungurian according to Wardlaw 2005, Permophiles (JA)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; limestone and red, blue claystone

• "limestones, often impure, with blue and red shales."

Size class: macrofossils

Collection methods: Romer (1928) paper is a review of vertebrates from the Texas red-beds with previously unreported (or undetailed) localities.
