“…Their frequent occurrence may also be connected with their roasting, which facilitates hazelnut cracking and grinding, destroys contaminants, induces a nutty flavour and digestion and, last but not least, enables their synchronous harvest (Mithen et al 2001;Mears, Hillman 2007;Holst 2010). Large amounts of hazelnut shells are known, for instance, from the sites of Duvensee, Germany (Holst 2010) or Staosnaig, Scotland (Mithen et al 2001). In the Czech Republic, finds of hazelnut shells are reported from Okrouhlík, Dolský Mlýn, Máselník, Pod Zubem, Pod Křídlem, Arba, Sojčí Převis, Jezevčí Převis, Kristova Jeskyně, Schwarzenberg Lake, Údolí Samoty, Dvojitá Brána u Rohlin, (Opravil 2003;Pokorný 2003;Komárková 2005;Pokorný et al 2008;Žáčková 2008;Svoboda et al 2013;Divišová 2014).…”
