Carrizo Arroyo (SDNHM coll) (Permian of the United States)

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

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• "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 mudstone

• Block faulting due to Ancestral Rocky Mountains tectonism

Size class: macrofossils

Preservation: mold/impression

Collection methods: Repository: San Diego Natural History Museum
