base notes	SBZ21 = DASH at base of Rupelian (Larger foram vs Planktonic zone diagram sent by R.Speijer, Feb’11 for GTS2012). Nummulites vascus and N. fichteli Zone. Base on SEPM chart corresponds to base of Oligocene. From Working Group on Larger Foraminifera website: "SBZZ 21 (early Rupelian). The base (correspondencing to the Eocene-Oligocene boundary) is defined by the first appearance of Nummulites fichteli and N. vascus, following the extinction of the discocyclinids. The upper limit corresponds to the first appearance of the lepidocyclinids in Europe. SBZZ 21 can be correlated to P18-19 and NP21 pars ? NP 23 pars zones. LBF Assemblages show high diversity: Nummulites bouillei, Operculina complanata, Spiroclypeus cf blanckenhorni ornate, Heterostegina spp., Neorotalia lithothamnica, N. verriculata, Halkyardia minima, H. maxima, Bullalveolina bulloides, Borelis sp., Praerhapydionina delicata, Austrotrillina paucialveolata, Peneroplis armorica.				comp notes
