Locality 37n (Pend Oreille Lake) (Cambrian of the United States)
Where: Idaho (48.0° N, 116.4° W: paleocoordinates 3.0° S, 83.0° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Lakeview Formation, Middle Cambrian (513.0 - 501.0 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
