Environment
Lithology: claystone
Taphonomic context: cave,human accumulation
Archaeology: stone tools
Habitat comments: "There are four main stratigraphic levels within the cave: Level 2 consists of compact yellow sediment with small ébouli. A small number of lithic artefacts have been found in the deposit. The characteristics of the lithic assemblage show that the site was used for the production of bladelets to make projectile and composed elements, maintenance of bladelet cores, repair of hunting tools, and treatment of animal carcasses".
Methods
Life forms: carnivores,ungulates
Sampling methods: quarry,screenwash
Sample size: 14 specimens
Years: 1990 - 1996
Sampling comments: "The excavation of the cave was conducted under the direction of M.R. Gonzâlez Morales and Diaz Casado between 1990-1996. Only 6 of the 16 m2 of the site has been excavated, mostly in the central part, which is the most inhabitable and spacious area of the cave. Some bones were recovered through sieving using a 2 mm mesh".
