Lakonis I (ca. 100,000-40,000 BP) is a collapsed Middle Palaeolithic cave on the coast of the Mani Peninsula of southern Greece. The site contains three distinctive components: a hearth context, upper bone breccia, and lower bone breccia. The bone breccias contain concreted deposits and large numbers of lithic and faunal materials, though the upper bone breccia preserves more evidence of dumping from hearth features. The hearth context is comprised of hearth lenses interspersed with mixed ashy sediments, which we interpret as the remnants of raked out and trampled combustion features. Bones and lithics in the hearth context have higher rates of burning, and the lithics are smaller and more broken. The large numbers of burned bones are probably not the result of accidental burning or the use of bone as a fuel source, rather they seem to relate to site maintenance. The incorporation of multiple lines of evidence points to two different site maintenance strategies at Lakonis: (1) the intentional burning of food refuse and (2) the cleaning of hearths, and dumping remnant deposits elsewhere at the site. We therefore consider Lakonis I to be amongst the growing list of sites that contain evidence for Neandertal behavioral complexity.
