Expeditious Available online 15 January 2016 technology was used here, aimed at producing very simple tools. Meat consumption has been detected along with, more notably, work on hides, wood and plant fibres which could be processed for string. Keywords: Only a small part of the San Quirce Neanderthals campsite has been dug to date. Nevertheless, it is a Open air campsite reference site in the search for evidence of Neanderthal patterns, cultural exchanges (learning, shared Neanderthals space) and resource administration (food, deferred consumption, differential object deposition, etc).

This assemblage provides valuable information for the reinterpretation of Neanderthal technological, economic, cultural and social capacities in an open air campsite. © 2015 Elsevier Ltd and INQUA.
