Environment
Lithology: not described
Taphonomic context: cave,midden
Habitat comments: "a limestone cave... it contains material that was evidently accumulated by woodrats (Neotoma)... Many of the bones recovered from Mescal Cave are acid etched, characteristic of bones that have been partially digested by raptors or mammalian carnivores"

Sampling methods: quarry,screenwash
Sample size: 1441 specimens
Sampled by: R. A. Stirton
Years: 1938
Sampling comments: fossils were "sifted" after being excavated, but "Mescal Cave sediments were not screened with a sufficiently fine mesh"
