Also known as CM locality 3692
Where: Elko County, Nevada (40.8° N, 115.7° W: paleocoordinates 44.1° N, 104.8° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Elko Formation, Early/Lower Uintan (46.2 - 39.7 Ma)
• "tentatively assigned to the Uintan Land Mammal Age" based on a zircon U-Pb date of 46.1 +/- 0.1 Ma for a tuff in the underlying lower member; a much younger U-Pb date of 38.9 +/- 0.3 Ma applies to the "topmost part" of the much higher upper member and is therefore not very relevant
• group of beds-level stratigraphic resolution
Environment/lithology: lacustrine deltaic; lithified, sandy limestone
Size classes: macrofossils, mesofossils
Preservation: adpression
