This volume is the third of a series which has evolved from the famous "Katalog der fossilen Dinoflagellaten, Hystrichosphären und verwandten Mikrofossilien" produced by Alfred Eisenack, one of the great pioneers of micropaleontology and co-workers Karl Klement and Göran Kjellström. The emphasis of the series is on taxa not included in the original series, but it is intended eventually to include all fossil dinoflagellate taxa. The series is organized as follows: 1) taxa of specific and lower rank are arranged in the alphabetical order of their final (or lowest ranking) epithet instead of being arranged in alphabetic order within each genus. The assignment of dinoflagellate species to genera may change but final epithets do not change once established, with the exception of possible minor orthographic corrections to their endings. 2) the basic language of the series is English rather than German. Diagnoses and descriptions are always provided in English as well as in the original language if that language is other than English and is written in, or can be easily transliterated into, the Roman alphabet. 3) entries are, or will be, provided for all taxa based on validly published names, regardless of whether the present editors, or any other author, regard them as taxonomic junior synonyms. 4) wherever possible, photomicrographs of the holotype of each species and infraspecific taxon are included. Additional photomicrographs and line drawings, where available and helpful in illustrating the original authors concept, may also be provided. The original "Katalog" also contained photomicrographs of the holotype for many taxa, but for others the holotype was not illustrated and sometimes only an interpretive line drawing by a subsequent author was included. 5) A cumulative reference list is included at the end of each volume of the series. Efficient communication of generic and species concepts is essential for accurate and detailed biostratigraphic analysis, which in turn is critical for accurate and detailed stratigraphie and basin modelling. In providing essential data for, and illustration of, key taxa, the new Eisenack Catalog is an indispensible tool for all researchers and industrial palynologists working with fossil dinoflagellates.weiterlesen
