Moqui Wash (Triassic of the United States)

Also known as UCMP V4126, V4127

Where: Coconino County, Arizona (35.1° N, 110.9° W: paleocoordinates 5.1° N, 38.4° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Wupatki Member (Moenkopi Formation), Spathian (251.3 - 247.2 Ma)

• About 21 m above underlying Kaibab limestone

•Lucas & Schoch (2002: Lethaia 35, 97-106) inferred the Wupatki Member to be Spathian in age based upon lithostratigraphic correlation.

Environment/lithology: "channel"; conglomerate and sandstone

• described as "mudflat" by Peabody (1948)

Size class: macrofossils

Preservation: trace
