Geography
Country: Spain
Coordinate: 43° 25' N, 4° 45' W
Basis of coordinate: based on political unit
Geography comments: "discovered in April 2011 during the excavation works for a highway in Llanes... in a cave placed under a sinkhole"
coordinate based on the municipality of Llanes
"The chronology of the fossil assemblage was determined by three AMS radiocarbon dates of 30, 275 ± 105 Cal ka BP (Beta—313518), 34, 235 ± 374 Cal ka BP (Beta—313520) and 36, 655 ± 205 Cal ka BP (Beta—313519), all falling within the MIS 3"

Climate and habitat
Substrate: ground surface
Lithology: limestone
Taphonomic context: pitfall trap
Habitat comments: "There was no clear stratigraphy in the fossiliferous deposits... the sinkhole acted as a natural trap... The possibility that carnivores or humans were responsible for the bone accumulation should be discarded since most of the fossils are well preserved"
Fig. 2 shows that the cave is formed in limestone and the excavated fossils were preserved in "debris" and "fluvial sediments"

Methods
Life forms: carnivores, ungulates
Sampling methods: quarry, surface
Sample size: 971
Years: 2011
Sampling comments: "Numerous large mammal bones were scattered over the cave floor... Fossil remains were recovered during an intensive exca- vation campaign in the summer of 2011, few weeks before the cave was definitively destroyed by the highway works"
