This is the first modern, extensive study of Late Cretaceous planktic foraminifera, a group of paramount importance for specialists in the oil industry and academia. This volume is dedicated to globotruncanids, describing 61 species with high-quality, spectacular photographs.
A major foraminifer diversification began in the Late Ordovician with multilocular tests. Their evolution saw walls change from agglutinated particles to microcrystalline calcite, leading to the major diversifications of the Mesozoic and Cenozoic Eras.
This book presents a new framework of foraminiferal descendence based on ancestor–descendant relationships. This methodology reveals key features evolved on multiple occasions, proving that classical classification should be abandoned for a new, descendence-based grouping.
For students and graduates, this textbook details the history of microfossil biostratigraphy and its core scientific concepts. It presents the practical uses of 25 microfossil groups and provides a numerical method to calculate their biostratigraphical resolution.
