Eagle Mountain (USGS 4165-CO) (Cambrian of the United States)

Where: California (36.2° N, 116.3° W: paleocoordinates 1.7° S, 95.1° 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; lime mudstone and shelly/skeletal wackestone

• The lithologies of the Jangle Limestone Member include lime mudstones, trilobite- and echinodermfragment wackestones, packstones, and grainstones, oolite, fenestral-fabric and laminated limestones.

Size classes: macrofossils, mesofossils, microfossils
