Where: New Mexico (34.8° N, 106.9° W: paleocoordinates 1.1° N, 36.5° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Red Tanks Member (Bursum Formation), Asselian (298.9 - 295.5 Ma)

• "In Carrizo Arroyo, a 100-m thick section through the Red Tanks Member of the Bursum Formation (late Virgilian)." Schneider et al., 2004. "Bursumian." Placement Carboniferous-Permian boundary has varied, but Lucas et al. (2013, 2016) correlated the two non-marine Lagerstatten with the early Asselian based on conodonts equivalent to the Streptognathodus nevaensis zone.
