NMMNH L-2810, Rio Salado (Triassic of the United States)

Where: Socorro County, New Mexico (34.3° N, 106.9° W: paleocoordinates 9.5° N, 46.0° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: San Pedro Arroyo Formation (Chinle Group), Norian (228.0 - 208.5 Ma)

• Suggested to be late Carnian, Adamanian LVF, but the Pedro Arroyo is correlated with the Bluewater Creek member of the Chinle Formation, suggesting that it is Norian in age.

• bed-level stratigraphic resolution

Environment/lithology: "channel"; sandstone and conglomerate

Size class: macrofossils

Reposited in the NMMNH
