base notes	DOTTED CP7-base marker; but moved to "other" because CP zones are no longer used in Paleogene. Agnini et al (2014) note "existing uncertainty with respect to its precise calibration to magnetostratigraphy". Their "?" dotted assignment (C25n.1 -- used here) is much higher than chron-age scaling of Berggren et al. (1995) of upper mid-Chron C25r. Alternate placement for base of NP8 also. IODP Expedition 320/321 Scientists (2010) assigned as 56.2 Ma (based on CK’95 scale) citing Agnini et al. (2007) implying placement at Chron C25n.3 on that CK’95 scale.				comp notes
