“…Tewari et al 2002) are generally sparse (Misra, 2001;Chauhan, 2006). The Siwalik Acheulian facies occurs sporadically in exclusive contexts as well as in surface association with Soanian assemblages, a trait also noted in parts of peninsular India (de Terra and Paterson 1939;Mohapatra 1981;Jayaswal, 1982;Ghosh, 1985), and is probably older than the latter (Chauhan, 2003;Gaillard and Mishra, 2001;Gaillard, 2006). Soanian artifacts were primarily manufactured on quartzite pebbles and cobbles, and assemblages generally comprise choppers, discoids, scrapers, cores, and numerous flake types, occurring in diverse typotechnological frequencies at individual sites (see Paterson and Drummond 1962).…”
