“…Different studies of prehistoric sites from the Middle East and Europe have demonstrated that phytolith analysis is a suitable tool to investigate fuel management, plant exploitation and the spatial organization of Neanderthal (Albert et al, 1999;Albert et al, 2000;Albert et al, 2003;Albert and Weiner, 2001;Cabanes et al, 2007;Henry et al, 2004;Karkanas et al, 2002;Madella et al, 2002) Recent geoarchaeological investigations at Esquilleu cave site have provided an example of a well preserved Late Pleistocene cave deposit containing a rich phytolith assemblage associated with abundant archaeological remains (Mallol et al, 2010). The chronology of the site corresponds to the Middle Paleolithic to Upper Paleolithic transition in Cantabrian Spain.…”
