NMMNH L-3433; Carrizo Arroyo (Permian of the United States)

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.

• group of beds-level stratigraphic resolution

Environment/lithology: pond; lithified, gray, green mudstone

• "Each DS consists mostly of red and purple, nonmarine mudstones and siltstones of a coastal plain environment and of greenish-gray, locally fossiliferous mudstones of a brackish to freshwater environment." Schneider et al., 2004
• "Both localities are in greenish-gray mudstone. This mudstone lithofacies appears massive, but locally a poorly developed fissility can be recognized. The mineralogic composition is similar to that of the purple and red mudstones/siltstones; these strata contain chlorite, illite, kaolinite, montmorillonite, rare other clay minerals, quartz, calcite and albite in varying amounts." Schneider et al., 2004

Size classes: macrofossils, mesofossils

Preservation: mold/impression, adpression

Reposited in the NMMNH
