(Table 3) Ranges of benthic foraminifers from the late Eocene through the Oligocene in ODP Hole 115-707A@en

Benthic foraminifers were counted according to the following scheme: 1 = present, 2 = 2 or more, 3 = 3-5, 4 = 5-10, 6 = 10-30, 7 = 30-50, 8 = 50-75, and 9 = 75-150. Because benthic foraminifers are not common in most samples, in many instances the numbers represent their true abundance in a sample. Only the bolivinids reached abundances of 6 or greater.底栖有孔虫（Benthic foraminifers）按照以下分级计数规则进行统计：1表示存在，2表示个体数量为2及以上，3对应3~5个，4对应5~10个，6对应10~30个，7对应30~50个，8对应50~75个，9对应75~150个。由于多数样本中底栖有孔虫并不常见，因此在多数情况下，该计数数值可反映对应样本中该类生物的实际丰度。仅包旋虫类（Bolivinids）的丰度达到6及以上。
