      abstract = {This second, completely revised edition of Paleogene  fossil birds gives a comprehensive, updated overview of the  avian fossil record from a geological period that lasted  from the end-Cretaceous mass extinction event (66 million  years ago) to the end of the Oligocene epoch (23 mya).  Paleogene avifaunas are highly diversified and not only  feature unusual archaic groups without close living  relatives but also offer unique insights into the evolution  and biogeographic history of extant birds. The main body of  the book constitutes an in-depth survey of the known  diversity of Paleogene avifaunas. The reader is introduced  into basic skeletal features of extinct avian taxa, with  these fossil forms being placed into a phylogenetic context  in the light of current hypotheses on the  interrelationships of extant birds. The geographical and  temporal occurrences of the various fossil groups are  outlined and their evolutionary significance is discussed.  Concluding sections inform more general aspects of  Paleogene avifaunas, such as possible causes of major  faunal changes. In addition to being a reference work for  the early evolution of modern birds from a  paleornithological perspective, the present work also  enables researchers in other fields of vertebrate  paleontology to gain an improved understanding of Paleogene  ecosystems. Numerous color photos of representative  specimens furthermore make the new edition attractive to a  wider audience interested in the avian fossil record.},
