• coordinate based on nearby landmark
• local area-level geographic resolution
When: Arroyo Formation (Clear Fork Group), Kungurian (279.3 - 272.3 Ma)

•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
