Where: San Miguel County, New Mexico (35.3° N, 104.4° W: paleocoordinates 10.3° N, 43.8° 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
