base notes	Base of Chattian (Early/Late Oligocene boundary ) GSSP is local higest common occurrence of planktonic foraminifer Chilogeuembelina cubensis at Monte Cagnero, Italy (although this highest-common is diachronous among ocean basins); with published placement at 15% up in Chron C9n at the GSSP (used here; with cycle-mag scale of Palicke for GTS2020). This constrasts with the interpreted astronomical interpretation of 27.82 Ma "option 1" (Coccioni et al., 2018) or 27.42 Ma "option 2". Previous working version had been base of Chron C10n.1n (same as GTS08). [NOTE: Base is potentially at ~70% up in "undifferentiated Chron C10n" in the GSSP in Italy (Coccioni et al., 2008), which would project as equivalent to C10n.1n.4.] Potentially at 2/3rds up in undifferentiated Chron C10n in candidate GSSP in Italy (Coccioni et al., 2008). <br><br> Assigned in GTS08 as base of Chron C10n.1n = Foram Zone P21a/P21b boundary (=LAD of common Chiloguembelina occurrence => last occurrence defines top of Rupelian, rather than an FAD defining base of Chattian) following Berggren et al. (1995). Ideally, this level would be at the base of polarity chron (C9r or C10n.1n), which provides a global marker.				comp notes
