Lower Wheeler Shale, loc: 712 (Cambrian of the United States)

Where: Millard County, Utah (40.0° N, 113.0° W: paleocoordinates 4.8° S, 91.7° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: Lower Wheeler Shale Formation, Delamaran (513.0 - 505.0 Ma)

• Listed as Middle Cambrian; Bolaspidella biozone

• bed-level stratigraphic resolution

Environment/lithology: slope; poorly lithified, gray shale

• Listed as Lower Slope, zone:5.5. Bob Gaines (personal e-mail, 11/6/2002 and 2002 GSA) notes this is fully anoxic, but better oxygenated than other Wheeler settings; "silt" is a diagenetic calcite; different facies actually identical hemipelagic calcareous shales with variation in carbonate content
• Medium-gray, thinly-bedded shale

Size class: macrofossils

Preservation: soft parts
