base notes	Agnini et al. (2014) draw as 92% up in C21r (used here). Nannotetrina cristata (and Nannotetrina spp.) begins 5 1/2 precession cycles (0.11 myr) above Lutetian GSSP (base of B. inflata) at Lutetian GSSP (Molina et al., 2011). Coincides with LAD of B. piriformis. In contrast, Agnini et al. (2014) and IODP Expedition 320/321 Scientists (2010) assigned higher as 48.0 Ma (based on CK’95 scale) citing Agnini et al. (2006) = 93% up in C21r on that scale. This is essentially same as the placement for a general "Nannotetrina" used by Leg 145 with FAD at base of Chron C21n. [Molina et al. (2011)]				comp notes
