base notes	DASH -- Agnini et al. (2014), citing Fornaciari et al. (2010) assign Top of C. grandis as 37.77 Ma according to P?like et al. (2006) cyclostratigraphy (used here). Middle of Chron C17n.2n at proposed Priabonian GSSP in Italy (Agnini et al., GSA Bull., 2011), which would be 37.98 on GTS2012 cycle-mag scale. This is one chron older than Berggren et al. (1995a) assignment as middle of Chron C17n.1n; but they indicate the LAD may occur approx. 2 myr earlier in Mediterranean. Normally, C. grandis does NOT overlap C. oarmaruensis. "Unfortunately, the LO of C. oamaruensis as well as the HO of C. grandis have a low degree of reproducibility in many areas because of their scarse abundances" (Agnini et al., GSA Bull., 2011).				comp notes
