base notes	SBZ22a = DASH at 35% up in P20 (Larger foram vs Planktonic zone diagram sent by R.Speijer, Feb’11 for GTS2012). Lepidocyclina and Bullalveolina Zone. Base on SEPM chart corresponds to base of Foram Zone P20. From Working Group on Larger Foraminifera website: "SBZZ 22 (late Rupelian-early Chattian) The base is defined by the appearance of Nephrolepidina praemarginata and Eulepidina formosoides, and the upper boundary by the appearance of the first Miogypsinoides. SBZZ 22 can be correlated with P20-P21 and NP23 pars-NP25 (lowermost part) zones. It corresponds to the Upper Rupelian and Lower Chattian. It can be divided into 2 subzones, SBZZ 22A and SBZZ 22B: * SBZZ 22A with lepidocyclinids, Nummulites and Bullalveolina; the upper boundary is marked by the occurrence of Cycloclypeus (C. mediterraneus lineage); * SBZZ 22B with lepidocyclinids, Nummulites and Cycloclypeus (C. mediterraneus lineage).				comp notes
