“…Fossil tree resins, commonly called ambers, are widespread and abundant in the geosphere, constituting a valuable source of paleobotanical and geochemical information (Grimalt et al, 1988;Anderson and Winans, 1991;Anderson et al, 1992;Wilson et al, 1992;Anderson and Botto, 1993;Anderson, 1994;Anderson and Crelling, 1995;Clifford et al, 1997;Alonso et al, 2000;Otto et al, 2002). Thus, their chemical composition provides evidence of their higher plant precursors and the diagenetic transformations that have occurred after deposition.…”
