(Table 1) Stratigraphical distribution of Cenozoic terrestrial palynomorphs from sediment core CRP-3 ...
Sparse low diversity early Oligocene spore-pollen assemblages above c. 410 mbsf (meters blow sea floor) in CRP-3 are dominated by Nothofagus pollen, and are very similar in composition to those from the lower part of CRP-2A. Anther-derived pollen aggregates, and a Nothofagus leaf at 44.12 mbsf show...
