NMMNH L-3252 (Triassic of the United States)

Where: McKinley County, New Mexico (35.4° N, 108.5° W: paleocoordinates 10.9° N, 47.1° W)

• coordinate estimated from map

• small collection-level geographic resolution

• Adamanian LVF; radiometric dates suggest that the Chinle is entirely Norian in age. Also known as the Bluewater Creek Member of the Chinle Formation. Low in formation.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; mudstone

Size class: macrofossils

Reposited in the NMMNH
