Also known as (Upper Vale Fm.) Main site

Where: Knox County, Texas (33.7° N, 99.6° W: paleocoordinates 2.4° N, 29.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: "Bullwagon" Member (Vale Formation), Kungurian (279.3 - 272.3 Ma)

• "Robert Roth, of the Humble Oil and Refining Company of Wichita Falls, Texas, believes that surfacer and subsurface data show that the beds in question are part of the 'Bullwagon' member of the Vale formation. This places the section high in the Vale, just below the Choza." Olson (1948 p. 190);

•the base and top of the Clear Fork Group (i.e., Arroyo, Vale, and Choza formations) are both within the Kungurian: see Wardlaw 2005 (Permophiles) for the base, and DiMichele et al. 2001 (J Paleont) for the top

• group of beds-level stratigraphic resolution

Environment/lithology: dry floodplain; pebbly, green, red conglomerate and lenticular siltstone

Size class: mesofossils

Collected by E. C. Olson, E. L. Yochelson, S. H. Mamay in 1946-1948, 1955; reposited in the FMNH

• Olson (1958) divided the locality into Quarry Site and Weathered Boulder Site, leaving the main one for recording scattered finds
