Calendar ages are estimated by interpolation between MIS boundaries from Fretzdorff et al. (2000) and correlation with global ice volume record by Labeyrie et al. (1987) / P/D intergrades encompass specimens that do not satisfy the sensu stricto definitions of neither N. pachyderma (dex) nor N. dutertrei.日历年代通过对Fretzdorff等人2000年研究中的海洋同位素阶段（Marine Isotope Stage, MIS）边界进行插值估算，并结合Labeyrie等人1987年的全球冰量记录进行关联校正得到。P/D过渡型类群（P/D intergrades）涵盖了既不符合严格意义上（sensu stricto）的右旋厚壳新方球虫（N. pachyderma (dex)）定义，也不符合杜氏新方球虫（N. dutertrei）定义的标本。
