Where: California (36.8° N, 117.1° W: paleocoordinates 1.3° S, 96.0° 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

•which characterize the Bristolia Zonule.
• member-level stratigraphic resolution
Environment/lithology: shallow subtidal; dolomitic, black, brown, argillaceous lime mudstone
•black, brown, and orange thin-bedded argillaceous
•dolomitic limestone which varies in argillaceous content
•throughout the study area.
Size classes: macrofossils, mesofossils, microfossils
