Where: Hidalgo County, New Mexico (31.6° N, 108.4° W: paleocoordinates 31.6° N, 108.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• "Thin Holocene deposits with cultural material directly overlie full-glacial deposits in some areas and mid-Wisconsin sediments in others. Animal burrows, slumping, and water action are apparent. In addition, mining of bat guano has removed much fill and greatly disturbed other areas."

•"Most faunal remains... are from the red guano unit, particularly from two deposits dated at 35 890 +/- 2640 and at older than 31 150 B.P. All dates from bulk samples of the sediments."

• group of beds-level stratigraphic resolution

Environment/lithology: cave; phosphorite

Size class: macrofossils

Collected in 1984

Collection methods: bulk, salvage, quarrying, surface (float), sieve,

• "sediments were screened through coarse (6 mm) and fine (1.8 mm) screens... most laboratory-processed material was wet-screened (0.5 mm mesh)... some areas were excavated by trowel without screening. Other material was recovered from mining spoil."

•taxonomic list is based on "approximately 433 catalogued items"
