UCMP V4204, Cameron (Triassic to of the United States)

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

• "mudflat"

Size class: macrofossils

Preservation: trace

Collected by Peabody; reposited in the UCMP
