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

• outcrop-level geographic resolution
When: Olenellus trilobite zone, Eagle Mountain Shale Member (Carrara Formation), Dyeran (516.0 - 513.0 Ma)
• Locally, thin limestone interbeds in the upper part of the member yield representatives of the Bristolia Zonule, which characterizes the overlying Thimble Limestone Member.
• member-level stratigraphic resolution
Environment/lithology: coastal; gray, green, silty shale and tabular packstone
Size classes: macrofossils, mesofossils, microfossils
