Our dataset points to a significant difference between these time intervals, however, as pliocene samples are significantly smaller than those in the pleistocene. In the tropics pliocene foraminifera are ~50 to 100 μm smaller than modern specimens at the same sst (~490 to 550 μm in the late pliocene to ~540 to 600 μm today).
Abstract: odp site 1123 has one of the most complete sequences of pliocene to early pleistocene calcareous biogenic sediments that has so far been recovered in the temperate southwest pacific. The sequence of planktic foraminiferal taxa and bioevents closely matches the one in dsdp site 284 and allows a good correlation between these oceanic sequences and the new zealand timescale.
