The zonations presented herein concern the two Cretaceous families Globotruncanidae and Heterohelicidae. The types of zones, their resolution and their geographical extent are briefly discussed and a table displays the vertical distribution of each index-species. From Berriasian to Maastrichtian, 33 zones are erected and their bottom and their top are defined in an annex. Most of the zones are calibrated with ammonites and/or with data from palaeomagnetic reversals.
