Studies with the foraminiferida have often been hindered by widely scattered, inaccessible sources. This two-volume reference (text in one volume, plates in the other) examines 3,568 of the world's generic taxa, representing all geologic ages. Covering twice the number of genera as any other available reference, it is by far the most complete source on the foraminiferida. The distinguished authors have assembled vital information on all supraspecific taxa of foraminifera, based on impressive advances made in the last twenty-five years in biology, morphology, and stratigraphy. Foraminiferal Genera and Their Classification provides an extensive supragenic classification, updated foraminiferal descriptions, comprehensive coverage of each genus, thorough attention to ultrastructure and internal anatomy, and precise stratigraphic data. Abundantly illustrated and fully explained, this text also features an extensive reference section. This book should be of interest to all those involved in the study of foraminifers.
