摘      要：The Cenozoic larger foraminifera are important for biostratigraphy in SE *** review examines the taxonomic inconsistencies of this group and especially the confusion over concepts of evolution,migration,radiation and *** is proposed that from the Mediterranean to Indo-Pacific,Latest Eocene through Miocene,larger foraminifera populations were more homogenous than previously *** show a slow morphological radiation interrupted by several *** pattern is superimposed on a long-term decline in larger foraminiferal *** dating of the major biostratigraphic events are *** main lineages of larger foraminifera can be classified by their evolutionary *** classically“largegenera have highly peramorphic trends achieved through strong orthoselection,and these lineages were the most severely hit by a series of Mid-Eocene to Mid-Miocene extinction *** carbonate facies taxa that are traditionally grouped with the larger foraminifera are characterised by weak paramorphism,and these were much less affected by the extinction *** of these weakly peramorphic forms underwent Latest Miocene to recent radiation to and locally become rock-forming *** three major and one minor larger foraminiferal extinction events since the Mid Eocene coincide with abrupt tectonic events across SE ***,there are probably multiple causes for these extinctions,including global climatic changes.
