Figure F3. Summary of the middle Miocene-uppermost lower Pliocene dinoflagellate cyst biohorizons and acme events from Hole 1151A, Leg 186, plotted against the downhole depth. Arrows = datum planes, open circles = acme events. R = rare (less than an average of 8 specimens per microscope traverse), C = common (8-15 specimens per microscope traverse), A = abundant (15-45 specimens per microscope traverse), and VA = very abundant (45 or more specimens per microscope traverse). NPD = code names for diatom biozone by Yanagisawa and Akiba (1998).
