USNM loc. 42247, Goldfield Hills (Cambrian of the United States)

Where: Nevada (37.6° N, 117.2° W: paleocoordinates 0.8° S, 91.7° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Elvinia trilobite zone, Emigrant Formation, Paibian (497.0 - 494.0 Ma)

• Furongian Series

• group of beds-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified shale

• The Emigrant Formation is found in the region between Tonopah,

•Nevada, and Death Valley, California. This thick package

•consists of carbonates and clastics that were deposited in outershelf

•to slope settings and include megabreccia-carbonadtee bris

•flows and pelagic and hemipelagic sediments. The formation

•has been subdivided into a 150 m lower limestone and

•siltstone member, 250 m (probably faulted and repeated) middle

•shale member, and 300 m upper limestone and chert member

•composed of ribbon limestones, interbeddeds hales, and megabreccia. the locality probably

•is in the "middle shale member"

• middle shale member

Size class: mesofossils
