Where: Baylor County, Texas (33.7° N, 99.3° W: paleocoordinates 2.2° N, 28.8° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Arroyo Formation (Clear Fork Group), Kungurian (279.3 - 272.3 Ma)
• "The beds average about 150 feet above the base of the Clear Fork." Details for Faunal Zone 4 of Romer 1928: "The vertebrate remains are confined to approximately the lowest 250 feet or so of the Clear Fork.."
•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: terrestrial; red claystone and conglomeratic sandstone
Size class: macrofossils
Reposited in the AMNH, BSP, FMNH, USNM
• Romer (1928) paper is a review of vertebrates from the Texas red-beds with previously unreported (or undetailed) localities.
