Geography comments: referred to as the "Silver Coulee quarry" by Jepsen, but Princeton Quarry by later authors
"sec. 21, T. 57 N., R. 100 W." (SE1/4 according to Rose 1981)
thought by Jepsen to be about 2400 feet above the base of the Fortin the Clark's Fork section, but 2200 feet above and in "the upper part of the Polecat Bench Formation" according to Rose (1981)
thought to be "intermediate in age" between Mason Pocket and Bear Creek and "later, but not latest, Tiffanian" (Rose 1981)
chron 25R according to Butler et al. (1981) (age estimate based on Ogg 2020)

Environment
Lithology: sandstone

Habitat comments: "a fine grained gray green sandstone" that is "almost a siltstone" according to Rose (1981)
specimens include "a number of articulated skulls and jaws, vertebral columns, limbs, and complete skeletons" with "little evidence of transportation"

Methods
Life forms: carnivores,primates,ungulates,other large mammals,other small mammals

Sampling methods: quarry

Sample size: 533 specimens

Museum: Princeton University, UMMP, MCZ

Sampling comments: metadata are from Jepsen except where noted, but the faunal list is from Rose (1981)
"discovered by G. L. Jepsen... in the late 1920s... Most of the collection... is at Princeton University. Smaller samples are housed at the University of Michigan and the Museum of Comparative Zoology"
12 additional species found in "close proximity" to the quarry are listed by Rose
