(Table 2) Distribution and abundance of late Cretaceous to early Paleocene nannofossils in DSDP Hole 89-585A

DEPTH, sediment [m] is given in mbsf. Species abundance: A = abundant (>10 specimens per field ov view at 780 X), C = common (1 specimen per field), F = few (1 specimen per 10 fields), R = rare (1 specimen per 100 fields), P = present (1 specimen per >100 fields), - = absent.

沉积物深度（单位：米）以海底以下米数（meters below seafloor，缩写mbsf）表示。物种丰度分级标准如下：
A（高丰度）：780倍放大倍率下，单个视野内标本数量大于10件；
C（常见）：单个视野内可见1件标本；
F（少见）：每10个视野内可见1件标本；
R（稀有）：每100个视野内可见1件标本；
P（存在）：每100个以上视野内可见1件标本；
-（无）：未检出。
