Figure F2. Dinocyst assemblage distribution through the Eocene-Oligocene transition among ODP Leg 189 Sites 1170-1172. Dinocyst association 1 = Antarctic-endemic, marginal marine, and eutrophic; association 2 = more cosmopolitan and more open marine; association 3 = coastal upwelling, open marine. For species composition and paleoecological discussion, see text. Lithologic units are from Exon, Kennett, Malone, et al. (2001).
