(Table 2) Range chart for stratigraphically important radiolarian species in ODP Hole 165-998B sediments@en

Sediment depth is given in mbsf. Species abundance estimates as follows: C = common, F = few, MR = moderately rare, R = rare, + = single specimen, - = searched for but not found, ? = dubious identification, and X = present in undetermined quantities.沉积物深度以海底以下米（meters below seafloor，mbsf）为单位。物种丰度估算标准如下：C表示常见（common），F表示少量，MR表示较稀有，R表示稀有，+表示仅见单个标本，-表示经搜寻但未发现该物种，?表示鉴定存疑，X表示丰度未明确。
