Gold Point, section GP-N 0 (Cambrian of the United States)

Where: Esmeralda County, Nevada (37.4° N, 117.3° W: paleocoordinates 3.4° S, 97.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Nevadella zone, Lower Mb. Member (Poleta Formation), Montezuman (530.0 - 516.0 Ma)

Environment/lithology: shallow subtidal; siliciclastic sediments

• in this section solenopleurids, corynexochids, and Bradyfallotaspis are about as abundant as the associated holmiids, but nevadiids are still the predominant trilobites. This nevadiiddominated mixed biofacies occurs in a relatively shallow, mixed carbonate-siliciclastic environment. Trilobites are occasionally

•common in the ribbon limestone and in the shaly middle unit of the lower member of the Poleta, but very rare, except as small fragments, in the carbonate grainstones.

Size classes: macrofossils, mesofossils
