5. Date: 2007-01-22 Page: 5 2. Cretaceous TSC NorLex Biostratigraphic Zonation (proposal) Digital TSC based zonation. Regionally applicable. One zone per stage i.e. Maastrichtian = MK1, Campanian = MK2 etc with subdivisions 1.1, 1.2 etc. Late Cretaceous: planktonic foraminifera & dinoflagellate cyst based.

6. Date: 2007-01-22 Page: 6 2. Cretaceous TSC NorLex Biostratigraphic Zonation (proposal) Strong zonal control on Cretaceous/Jurassic boundary (`base `Cretaceous unconformity`) Use of Berriasian/Tithonian Emphasis on marine planktonic markers unless prefixed otherwise [B]: Benthic Foraminifera, [R] Radiolaria [S] Spores/Pollen etc
