Geography
Country: Spain

State: Cantabria



Coordinate: 43° 14' 47" N, 3° 27' 4" W
Coordinate basis: stated in text

Time interval: Holocene

Section: 3786

Unit number: 1

Unit order: above to below

Ma: 0.01012

Age basis: radiocarbon (calibrated)

Geography comments: "El Mirón is a large cave in the upper Ason River Valley of the Cantabrian Cordillera of northern Spain"
The Azilian level of the site has been radiocarbon dated to 10,120 cal. BP

Environment
Lithology: not described

Taphonomic context: cave,human accumulation

Archaeology: hearths,stone tools

Habitat comments: The cave was used fairly continuously by humans. The entire Magdalenian and Azilian cultural periods contain abundant lithic assemblages, associated with hearth remains. Humans were the principal bone accumulators of the large mammal assemblage, while birds of prey (owls) were likely responsible for the gathering of small mammal fauna.

Methods
Life forms: ungulates

Sampling methods: quarry,screenwash

Sample size: 24 specimens

Years: 1996 - 2000

Sampling comments: "Sediments were washed through a graded series of sieves, from 2 cm to 1 mm, and were water-screened through fine mesh for the recovery of small vertebrate remains. This produced a rich and species-diverse assemblage of mainly rodents and insectivores, though also small carnivores, bats, lagomorphs, fishes, amphibians, reptiles and birds".
"A total of 5200 ungulate remains were identified, taxonomically distributed across 7 species". These are the only identified remains with NISP data reported; the numerous remains of small mammals are only given as MNI, of which there are "a minimum of 1915 individuals across 22 species".
