Drum Mountains (Cambrian of the United States)

Where: Millard County, Utah (39.5° N, 113.0° W: paleocoordinates 4.6° S, 91.6° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Wheeler Formation, Middle Cambrian (509.0 - 497.0 Ma)

• 30 m from the top of the formation

• bed-level stratigraphic resolution

Environment/lithology: paralic; lithified shale

• The uppermost 45 m of the Wheeler Shale consists of shallow subtidal and peritidal lithologies with sedimentary structures that indicate well-protected environments, which were occasionally disturbed by high-energy storm waves.

Size class: macrofossils
