(Table 4) Planktic foraminiferal abundance in Oligocene to Early Miocene sediments of ODP Hole 177-1090E on the Agulhas Ridge, South Atlantic@en

Species abundance: S = scattered (1-3 specimens), R = rare (<10 %), F = few (3-15 %), C = common (15-30 %), A = abundant (30-50 %), D = dominant (>50 %), - = not present, specimens considered as reworked are not reported物种丰度（Species abundance）分级标准如下：S=分散型（1~3件标本），R=稀有（占比<10%），F=少见（占比3%~15%），C=常见（占比15%~30%），A=丰富（占比30%~50%），D=优势类群（占比>50%），符号“-”代表类群未出现；经判定为再沉积的标本不予记录。
