Where: Baylor County, Texas (33.6° 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 perhaps average 200 feet above the Lueders" Limestone. 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.."

• group of beds-level stratigraphic resolution
Environment/lithology: terrestrial; red claystone and conglomeratic sandstone
Size class: macrofossils
