Else Marie Friis is Professor and Head of Department at the Swedish Museum of Natural History. Her research interests include Cretaceous flowers and other reproductive structures with particular focus on the origin and early diversification of angiosperms and related seed plants. Peter R. Crane is Professor and Carl W. Knobloch, Jr, Dean at the School of Forestry and Environmental Studies, Yale University. His research interests include large-scale patterns and processes of plant evolution, integrated palaeobotanical and neobotanical studies of plant diversity, and evolution. Kaj Raunsgaard Pedersen is Emeritus Professor at the Department of Geology, University of Aarhus. His research interests include integrated palynological and palaeobotanical studies of Mesozoic seed plants with particular focus on Cretaceous reproductive structures and flowering plant evolution.

• Preface; 1. Introduction to angiosperms; 2. The nature of the angiosperm fossil record; 3. The environmental context of early angiosperm evolution; 4. Stratigraphic framework and key areas for Cretaceous angiosperms; 5. Angiosperms in context: extant and fossil seed plants; 6. Origin and age of angiosperms; 7. Phylogenetic framework and the assignment of fossils to extant groups; 8. Fossils near the base of the angiosperm tree; 9. Early fossil angiosperms of uncertain relationships; 10. Early fossils of eumagnoliids; 11. Fossils of monocots; 12. Fossils of eudicots: early diverging groups; 13. Fossils of core eudicots: basal lineages; 14. Fossils of core eudicots: rosids; 15. Early fossils of eudicots: asterids; 16. Patterns of structural diversification in angiosperm reproductive organs; 17. History and evolution of pollination in angiosperms; 18. History and evolution of dispersal in angiosperms; 19. Vegetational context of early angiosperm diversification; 20. The accumulation of angiosperm diversity; References; Index.

'… this book provides not only facts but also many potential questions and can thus serve as both an inspirational textbook [and] as a recipe for future research investigations. … an important book for those wishing a fuller understanding of floral evolution. Buy it, read it, discuss it, and you will achieve sexual enlightenment of the floral kind.' Plant Science Bulletin
