Meteor Crater Quarry, main bonebed (Triassic of the United States)

Also known as UCMP V3835

Where: Coconino County, Arizona (35.0° N, 111.0° W: paleocoordinates 5.2° N, 38.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• Three fossil vertebrate horizons occur at Meteor Crater - the middle of these is the main quarry.

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

• bed-level stratigraphic resolution

Environment/lithology: lacustrine; calcareous sandstone and red mudstone

• Freshwater lake or pond
• "occurs in both the blockly fine red mudstone and a limey sandstone. Most of the remains are encased in the limey sandstone"

Size class: macrofossils

Collected by Camp, Welles in 1938, 1939, 1941, 1958, 1965; reposited in the UCMP
