(Table T2) Paleogene-lower Miocene nannofossil stratigraphy of ODP Hole 198-1208A sediments@en

Sediment depth is given in mbsf. Selected Cretaceous samples and marker species are included. Species abundance as follows: A = abundant (>10 specimens per field of view [FOV]), C = common (1-10 specimes per FOV), F = few (1 specimen per 2-10 FOV), R = rare (1 specimen per 11-100 FOV), VR = several specimens only. Chronostratigraphic designations are approximate, but precise correlations can be found on the ODP Leg 198 timescale (Bralower, Premoli Silva, Malone, et al., 2002, doi:10.2973/odp.proc.ir.198.2002).沉积物厚度以米海底以下（meters below sea floor, mbsf）为单位标注。本数据集纳入了筛选得到的白垩纪样品与标志种。物种丰度分级标准如下：A为丰富（单视野内标本数>10），C为常见（单视野内标本数1~10），F为少量（每2~10个视野可见1个标本），R为稀有（每11~100个视野可见1个标本），VR为仅见数个标本。本次所用的年代地层划分仅为近似值，精确地层对比可参考大洋钻探计划（Ocean Drilling Program, ODP）第198航次的年代标尺（Bralower、Premoli Silva、Malone 等，2002，doi:10.2973/odp.proc.ir.198.2002）。
