(Table 9) Ranges of benthic foraminifers through the Oligocene in ODP Hole 115-710A@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）按照以下分级方案进行计数：1代表存在，2代表2个或更多，3代表3~5个，4代表5~10个，6代表10~30个，7代表30~50个，8代表50~75个，9代表75~150个。由于大多数样品中底栖有孔虫并不常见，因此多数情况下该分级数值可代表样品中其实际丰度。仅玻尔夏有孔虫类（bolivinids）的丰度达到6级及以上。
