Where: California (36.5° N, 116.7° W: paleocoordinates 1.4° S, 94.8° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Albertella trilobite zone, Jangle Limestone Member (Carrara Formation), Delamaran (511.2 - 506.5 Ma)
• The lower part of the Jangle Limestone Member in the southeastern part of the outcrop area of the Carrara Formation has yielded several small low-diversity collections of trilobites that are typical of the Albertella-Mexicella Zonule of the Albertella Zone.
• member-level stratigraphic resolution
Environment/lithology: shallow subtidal; gray, white lime mudstone and burrowed, black mudstone
•light-gray or white laminated limestone to black burrowed
•mudstones are evident in the sections at Echo
•Canyon, Pyramid Peak, and Eagle Mountain.
Size classes: macrofossils, mesofossils, microfossils
