Also known as HG#492.1

Where: Nevada (37.7° N, 117.2° W: paleocoordinates 3.5° S, 96.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Nevadella trilobite zone, Poleta Formation, Montezuman (520.0 - 515.3 Ma)

• AGE: Nelson (1976, 1978) places the Poleta Formation on the boundary between the Nevadella and Bonnia-Olenellus trilobite zones, with the lower Poleta Formation (from which this collection is described) within the Nevadella zone; age revised by A. Hendy (5/2009) from "Cambrian" to Montezuman following Streng et al. (2005).

• member-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified, hardground limestone

Size classes: macrofossils, mesofossils, microfossils
