“…Artefact properties, such as size profiles, abrasion, rounding, spatial distributions, and orientations, are commonly used as proxies of preservation for archaeological assemblages (e.g., Isaac, 1967;Schick, 1984Schick, , 1986Bertran and Texier, 1995;Shea, 1999;Lenoble and Bertran, 2004;McPherron, 2005;Kuman and Field, 2009;Bernatchez, 2010;Braun et al, 2013;Hovers et al, 2014;Lotter et al, 2016). With reference to the latter, in recent years spatial analysis using Geographic Information System (GIS) techniques has increasingly been used (Alperson-Afil et al, 2009; Benito-Calvo and de la Torre, 2011; Gallotti et al, 2011;Böhner et al, 2015;de la Torre and Wehr, in press).…”
