Geography
Country: Mexico

State: Chihuahua



Coordinate: 29° 24' N, 107° 55' W
Coordinate basis: based on nearby landmark

Time interval: Holocene

Max Ma: 0.00134

Min Ma: 0.000575

Age basis: radiocarbon (uncalibrated)

Geography comments: "within the Babícora Basin... A large lake, the Laguna de Babícora, lies about 10 km southeast" (coordinate based on El Zurdo)
there is a radiocarbon date of 1340 +/- 80 B.P. on a corn cob and two calibrated dates of A.D 1288 and A.D. 1375 on "two human skeletons in a double burial" (intcal3 back computation of the dates yields 683 and 575 B.P.)

Environment
Lithology: not described

Taphonomic context: human accumulation,midden,settlement

Archaeology: buildings,burials,ceramics

Habitat comments: there are "three main roomblocks of adobe and rock wall construction, all of which have been disturbed by pothunting. There is also a patio area and a large midden deposit" and there is "polychrome pottery"

Methods
Life forms: carnivores,rodents,ungulates,other small mammals,birds,turtles,frogs,fishes

Sampling methods: quarry,screenwash

Sample size: 825 specimens

Years: 1991, 1992

Sampling comments: "There was a great deal of site disturbance fro pothunting and the large rodent population on the site no doubt helped to mix the deposits" so a listed "pig" specimen is probably intrusive
excavation "targeted the central roomblock and the midden area" and sediment was "screened through quarter-inch mesh"
counts of turkey specimens recovered from "five turkey burials" are excluded
