Where: Navajo County, Arizona (34.9° N, 110.2° W: paleocoordinates 3.2° N, 38.8° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Holbrook Member (Moenkopi Formation), Aegean to Aegean (247.2 - 242.0 Ma)
• Lucas & Schoch (2002: Lethaia 35: 97-106) inferred the Holbrook member to be earliest Anisian (Aegean–Bithynian) in age based upon tetrapod biostratigraphy (Eocyclotosaurus used to correlate Holbrook Member to German Upper Bundsandstein) and magnetostratigraphy
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size class: macrofossils
Collected by S. Welles in 1949, 1965, 1966; reposited in the UCMP
