^aBiostratigraphy and magnetostratigraphy were aligned to the GTS2012 time scale [Gradstein et al., 2012]. New Planulina wuellerstorfi δ¹⁸O minima and maxima [Elmore et al., 2015]; Kender et al. [2016], and this study] were visually aligned with key isotope stages in the LR04 benthic δ¹⁸O stack [Lisiecki and Raymo, 2005]. Linear sedimentation rates were assumed between all tie points.
