Locality 37n (Pend Oreille Lake) (Cambrian of the United States)

Where: Idaho (48.0° N, 116.4° W: paleocoordinates 3.0° S, 82.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Lakeview Formation, Middle Cambrian (509.0 - 497.0 Ma)

Environment/lithology: lithified, black limestone and lithified shale

• "Where unaltered, two rock types characterize this conspicuous and commercially valuable formation. One type consists of cliff-forming massive beds which vary from nearly pure limestone to nearly pure dolomite. The other beds are shaly, containing thin-bedded, highly fossiliferous limestone...black crystalline limestone from the shaly beds yields an abundant fauna."

Size class: macrofossils

Reposited in the USNM
