Cenozoic silicoflagellates and ebridians from ODP Leg 113 ...
Silicoflagellates are present at ODP 113 Sites 689, 690, 693, 695, 696, and 697. These are generally Neogene in age except for Oligocene and Eocene silicoflagellates and ebridians at Sites 689, 690, and 693, and Lower Cretaceous (Albian) silicoflagellates at Site 693 (the latter are described in McC...
