NMMNH L-404, Garita Creek (Triassic of the United States)

Where: San Miguel County, New Mexico (35.3° N, 104.5° W: paleocoordinates 10.3° N, 43.9° W)

• coordinate estimated from map

• small collection-level geographic resolution

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

• Considered to be late Carnian (Adamanian) in age by the authors; however, recent radiometric dating suggests a Norian age for most or all of the Chinle. The Garita Creek Formation was formerly referred to as the "lower shale member of the Chinle Formation"

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; conglomerate

Size class: macrofossils

Reposited in the NMMNH
