Resting Springs Range (USGS 3675-CO) (Cambrian of the United States)

Where: California (36.1° N, 116.2° W: paleocoordinates 1.8° S, 96.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Olenellus trilobite zone, Thimble Limestone Member (Carrara Formation), Dyeran (515.3 - 511.2 Ma)

• This member typically has abundant and diverse olenellid trilobites and rare associated ptychopariid trilobites which characterize the Bristolia Zonule.

• member-level stratigraphic resolution

Environment/lithology: shallow subtidal; gray limestone and red, argillaceous limestone

• In the Striped Hills and Resting Springs Range each couplet is a graded bed, the lower gray part consisting of a fine calcarenite that overlies an erosion surface and grades into the overlying orange argillaceous upper part.

Size classes: macrofossils, mesofossils, microfossils
