“…Although geomorphology data exist on patterns of clast orientation in non-artifactual deposits, fewer studies focus on patterns of artifact orientation in archaeological sites. However, there are exceptions, exemplified by early studies using orientation analysis that focused on sites in fluvial environments (Issac, 1967;Bar-Yosef, 1972;Kroll and Isaac, 1984;Schick, 1984Schick, , 1987Kaufulu, 1987;Bertran and Texier, 1995) and recent research that utilizes a fabric analysis to understand site-formation processes (Bertran and Texier, 1995;Kluskens, 1995;Dibble et al, 1997;Sahnouni and de Heinzelin, 1998;Esdale et al, 2001;Todd et al, 2001;Byers, 2002;Lenoble and Bertran, 2004;McPherron, 2005;Dibble et al, 2006;Enloe, 2006;Rapson et al, 2007;Bernatchez, 2010).…”
