Figure F35. Sand content at Site 1086 for the last 6 m.y., compared with (A) the ratio of benthic to planktonic foraminifers and with (B) the abundance of Hoeglundina elegans, an aragonitic benthic species. Note the shorter time span in B. P/P = Pliocene/Pleistocene boundary, G/M = Gauss/Matumaya reversal, BF = benthic foraminifer, PF = planktonic foraminifer, MP = Miocene/Pliocene boundary.
