This volume contains 15 English-language contributions to the?Symposium on the Paleogene? organized by Noël Vandenberghe in Leuven (Belgium) in August 2003 under the auspices of the International Subcommission on Paleogene Stratigraphy which is part of the International Commission on Stratigraphy of the International Commission of Geological Sciences. The objective of this subcommission is to encourage research into the Paleogene by establishing working groups dealing with specific problems, in particular the agreement on an international set of stages and series defined by boundary stratotypes, and organizing general symposia and thematic meetings. Ph.D.Gingerich demonstrates that the increase in diversity of the vertebrates is greatest during the late Paleocene and early Eocene and stresses the importance of the Paleogene for the understanding both vertebrate history back to the deeper past and forward to the present Two papers are dedicated to the evolution of the foraminiferal faunas at the Cretaceous/Paleogene boundary. Alegret et al. establish a succession of events affecting the foraminiferal faunas in the Tethyan and Gulf of Mexico across the boundary interval. The planktonic foraminiferal extinction patterns during the Campanian-Maastrichtian and at the Cretaceous/Paleogene boundary studied in detail by El-Sabbagh et al. in two sections of the Western Central Sinai represent?normal? background extinctions below the Cretaceous/Paleogene boundary, whereas the extinction of 45 species at the boundary level is compatible with the effects of a large meteorite impact. The study of the larger foraminifera of the Paleogene succession of the Island of Masirah (Oman) allows to recognize early to middle Lutetian and early Oligocene shallow-marine carbonates (Menkfeld-Gfeller Decrouez). The critical species are discussed and illustrated. The biostratigraphy of the middle to late Eocene part of the Valle della Contessa and the Monte Gagnero sections in Central Italy is revised by Verducci Nocchi based on planktonic foraminifera determined mainly in thin section. Problems in the correlation with the magnetostratigraphy and the boundaries of the Paleogene stages are discussed. The numerous illustration of the planktonic foraminiferal species are very useful for studies of Paleogene carbonates restricted to thin sections.
