Environment
Lithology: limestone
Taphonomic context: cave
Habitat comments: "the sediments are mostly derived from within the cave by weathering of the limestone and calcite crystals... It is difficult to say if any other animals besides wood rats contributed to transporting fossils into the cave... Clearly no inorganic processes such as wind, water, or gravity could have been responsible for the fossil deposits"
Methods
Life forms: herbs,bats,carnivores,rodents,ungulates,other small mammals,birds,lizards,fishes,scarab beetles,other arthropods,snails
Sampling methods: quarry,screenwash
Sample size: 9651 specimens
Years: 1977, 1981, 1982
Sampling comments: "Sediment was also taken to the lab in bags and screened"
