Where: Coconino County, Arizona (35.8° N, 111.5° W: paleocoordinates 4.5° N, 39.3° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Holbrook Member (Moenkopi Formation), Aegean to Aegean (247.2 - 242.0 Ma)
• upper Moenkopi, about 18 m below contact with overlying Shinarump. 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; mudstone
Size class: macrofossils
Preservation: trace
