Supplementary Table 2. NKK1 borehole planktonic foraminifera range chart and biozone assignments. Assemblages were analysed to species level based on examination of the >150 µm and 63-150 µm sieve. Relative abundance categories: abundant (A), common (C), rare (R) and single (S). Note that not all samples were examined. Species in red font are those important for biostratigraphic zonal assignments and the age model. NB. We show the occurrence, in one sample (NKK-1/52, 70–78cm) of the recently described species Globoturborotalita barbula Pearson and Wade 2015 in this range chart. This species was described after our general NKK-1 assemblage work, and thus was not originally recognized, However, since paratypes of this new species are derived from the NKK-1 Javanese material we can now at least record this occurrence. Pearson and Wade (2015) write "Globoturborotalita barbula n. sp. is a common component of the Tanzanian assemblages both before and after the Eocene/Oligocene boundary and we have also confirmed that it is equally common in the Eocene/Oligocene transition of Java (unpublished data)."
