UCMP V4603, Rockville (Triassic to of the United States)

Where: Washington County, Utah (37.2° N, 113.0° W: paleocoordinates 6.3° N, 39.8° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Torrey Member (Moenkopi Formation), Aegean to Aegean (247.2 - 242.0 Ma)

• Upper red member is equivalent to the Holbrook Member of Arizona.

•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; sandstone

Size class: macrofossils

Preservation: trace
