Environment
Lithology: limestone
Taphonomic context: lake deposit
Habitat comments: the limestone is interpreted as having deposited in "a warm, heavily vegetated, shallow, permanent lake, with slow-moving currents"
teeth, jaws, skulls, and "larger bones" are all present

Methods
Life forms: bats,carnivores,primates,rodents,ungulates,other large mammals,other small mammals
Sampling methods: quarry
Sample size: 195 specimens
Years: 1975 - 1977, 1979, 1980
Museum: USNM
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
