(Table 3) Distribution of calcareous nannofossils in the Eocene of ODP Hole 113-690B@en

Relative individual species abundance: V = very abundant (>10 specimens/field of view). A = abundant (1-10 specimens/field ov view), C = common (1 specimen/2-10 fields of view), F = few (1 specimen/11-100 fields of view), R = rare (1 specimen/101-1000 fields of view), P = present (only 1 specimen observed/slide). Reworked specimens are denoted by lower case letter.物种个体相对丰度分级标准如下：V级为极丰富（单视野内标本数＞10个）；A级为丰富（单视野内标本数1~10个）；C级为常见（每2~10个视野内可见1个标本）；F级为少量（每11~100个视野内可见1个标本）；R级为稀有（每101~1000个视野内可见1个标本）；P级为检出（每张载玻片仅观测到1个标本）。再沉积标本以小写字母标注。
