In this book, evolutionary classification and nomenclature in the Cretaceous planktic foraminifera with at least one stage with chambers alternately added with respect to the test growth axis are analyzed in seven articles. The first article in this book presents new data about the group's evolutionary origin and different aspects of the iterative evolution of the planktic habitat in the foraminiferal history, together with a critical review of some past ideas on this topic. A new benthic foraminiferal genus is described. The evolution of different lineages is presented in five successive arti.
