“…On the contrary, considerable lithic assemblages associated to the Middle Palaeolithic (Zagros Mousterian; Dibble, 1984) and Upper Palaeolithic (Zagros Aurignacian: Olszewski and Dibble, 1994;Baradostian: Solecki, 1958;Rostamian: Conard and Ghasidian, 2011 ) are known to be concentrated in the Zagros foothills (mainly in caves and rock shelters) (e.g., Biglari, 2001;Otte et al, 2007;Shidrang et al, 2016;Bazgir et al, 2017;Heydari-Guran and Ghasidian, 2017). Beyond the Zagros foothills, several open-air sites in stratigraphic context have recently been discovered in the northern and western edges of the Iranian Central plateau, as well as the central Alborz (e.g., see Berillon et al, 2007;Berillon and Asgari Khaneghah, 2016;Conard et al 2009;Heydari-Guran et al 2014;Vahdati Nasab and Hashemi 2016;Vahdati Nasab et al, 2013;2019). Notwithstanding this abundant archaeological evidence, the debate suffers from a lack of chronological data for this area.…”
