“…Many palaeoecological-research studies have been carried out on palynology of cave sediments, including bat guano and coprolites from other taxa and surface soil in different part of the globe, such as in Romania (Pop and Ciobanu, 1950;Boscaiu and Lupsa, 1967a,b;Feurdean et al, 2011;Geanta et al, 2012), the United States (Sears and Roosma, 1961;Davis, 1990;Nieves-Rivera 2003;Maher, 2006;Batina and Reese, 2011), Switzerland (Groner, 2004), Austria (Kral, 1968;Draxler, 1972), the UK (Coles et al, 1989;McGarry and Caseldine, 2004), Spain (Carrió n, 1992;Carrió n et al, 1999Carrió n et al, , 2006Navarro Camacho et al, 2000, 2001, Belgium (Bastin, 1978;Bastin et al, 1986), Nepal (Denniston, et al, 2000), China (Qin et al, 1999;Zhang et al, 2004), and other parts of Asia (Hunt and Rushworth, 2005). In India, no previous studies have addressed the use of bat guano in cave sediments for palaeoecological study.…”
