Where: Esmeralda County, Nevada (38.0° N, 118.0° W: paleocoordinates 37.8° N, 113.9° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Esmeralda Formation, Clarendonian (12.5 - 9.4 Ma)

• other than biochronology, there is no particular evidence for the stratigraphic position of this locality relative to the Stewart Spring and Cedar Mountain faunas

•dates of Evernden et al. 1964: KA 480 - 11.1 (= 11.39) Ma, 25' above micromammals KA 499 - 11.4 (= 11.70) Ma, just below micromammals

•average is 11.545 Ma

•these dates are not discussed by Perkins et al. 1998

Environment/lithology: terrestrial
