NMMNH L-3251, Fort Wingate (Triassic of the United States)

Where: McKinley County, New Mexico (35.4° N, 108.6° W: paleocoordinates 10.9° N, 47.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Bluewater Creek Formation (Chinle Group), Norian (228.0 - 208.5 Ma)

• Adamanian LVF; radiometric dates suggest that the Chinle is entirely Norian in age. Also known as the Bluewater Creek Member of the Chinle Formation. 40 m above base of formation, 20 m below Blue Mesa Mbr, at approx. level of McGaffey Mbr (absent at this locaity)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithified conglomerate

• "a very well-indurated intraformational conglomerate"

Size classes: macrofossils, mesofossils

Reposited in the NMMNH
