Where: Coconino County, Arizona (35.9° N, 111.1° W: paleocoordinates 14.9° N, 50.4° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Wingate Sandstone Formation (Glen Canyon Group), Rhaetian to Rhaetian (208.5 - 199.3 Ma)
• Wingate traditionally identified as Early Jurassic in age; however, Lucas et al. (2011: Palaeo3 302: 194-205) have argued that the lower part of the Wingate is latest Triassic in age. Because the position of the boundary relative to this locality is unclear, it is assigned a Rhaetian–Hettangian age.
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size class: macrofossils
Preservation: trace
Collection methods: surface (in situ),
