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)

"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
