Where: White Pine County, Nevada (39.5° N, 115.4° W)

• Paleocoordinates: 2.3° S, 48.5° W (Wright 2013)

• coordinate estimated from map

• small collection-level geographic resolution

When: Cravenoceras hesperium zone, Diamond Peak Formation, Pendleian (330.9 - 327.0 Ma)

• JA: ammonoid zone is "early Namurian" = Serpukhovian and "equivalent to the lower part of foraminiferal Zone 18" of Mamet and Skipp 1970, which is early Serpukhovian = Pendleian

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; poorly lithified, pebbly, sandy, calcareous limestone

• a pebbly limestone bed, weathered into a tan porous layer resembling punk and contains almost completely weathered out fossil shells held in place by a weak sandy calcareous binder.
