Age basis: AEO

Geography comments: "near Ely" and shown as immediately south and slightly west of the town in FIg. 1 (coordinate based on Elderberry Canyon)
correlated with the "lower part, or Black's Fork Member, of the Bridger Formation"

Environment
Lithology: limestone

Taphonomic context: lake deposit

teeth, jaws, skulls, and "larger bones" are all present

Methods

Excluded forms: birds, frogs, clams, snails

Sampling methods: quarry

Sample size: 195 specimens

Years: 1975 - 1977, 1979, 1980

Museum: USNM

Net or trap nights: 0

Basal area status: not applicable

Sampling comments: "discovered in the summer of 1975 by Dr. Thomas Fouch, his daughter Melissa Fouch, and Forrest G. Poole... who collected several blocks... of bone-bearing limestone.... Additional blocks of limestone were collected in 1976" and "in 1977, 1979, and 1980"
the limestone was prepared "in a dilute formic acid" in multiple cycles
"small anuran amphibians and small reptiles are represented by many specimens that are not yet sorted and identified. Birds are represented by several limb elements too poorly preserved to allow identification"
"bivalve and gastropod molluscs, and unidentified ostracodes" are also present
