Foraminiferal genera and their classification. Two volumes

Abstract

Volume 1 contains the text of the treatise, and volume 2, 847 plates. Of the 3620 validly proposed generic taxa of Foraminiferida considered 2455 genera are recognised, described and illustrated, 960 regarded as synonyms, 208 considered systematically unrecognisable, 16 too late for detailed inclusion. They are placed in 12 suborders, 74 superfamilies, 296 families, 302 subfamilies. A systematic index is included. The systematic arrangement of genera is alphabetical within the various subfamily or family categories, and the family group taxa within the suborders are arranged in order of presumed evolutionary sequence or increasing complexity. Descriptions are generally focused on test morphology, both external and internal, but some information concerning the living organism is summarized for the few that are known. Geologic range is given to the level of the geologic series of epoch, and known geographic occurrence and a limited amount of ecologic information is included. In view of the very large number of taxa considered, morphologic descriptions are as concise as possible, consistent with the inclusion of the available information. Morphologic terms used are defined in a glossary, in which reference also is given to other terms proposed by various writers. -from Authors
