The evolutionary origin and early history of the angiosperms (or flowering plants), which are the dominant land plants today, has remained an unsolved problem since the time of Darwin. It has been referred to since those days as an 'abominable mystery', because neither direct ancestor nor an agreed date could be determined. Mr Hughes argues that previous approaches, mostly through botanical theory, have been inadequate and misleading. He suggests that the date is about 110 million years ago (in the Cretaceous period) and there is a good chance of ancestors being found if the correct approach is adopted to the study of other fossil plants of that period. Moreover, the study of plant microfossils in the past twenty years has made feasible a fuller geological study of other fossils. When this book was first published in 1976, several reviewers saw it as a timely book on a controversial subject.

This book covers the hot topics of angiosperm structure and evolution in several chapters discussing vegetative and reproductive characters. It also looks at the implications of ancestral angiosperm characters for an herbaceous origin and the phylogeny of angiosperms from a structure and molecular perspective.

This book was originally published in 1989. The dramatic radiation of the angiosperms towards the end of the Early Cretaceous initiated major changes in terrestrial ecosystems throughout the world. Dramatic changes in the flora and fauna were exemplified by the development of angiosperm-dominated plant communities and the rapid diversification of mammals, birds and insects. Written specifically for use by advanced undergraduate and graduate students, the book presents an overview of works on the origins of angiosperms and the ecological effects upon terrestrial life of their rapid radiation. It will be of particular value to students of palaeobiology and ecology, as well as to those studying evolutionary biology and systematics.

Angiosperms are the most diversi ed plant group in the world, being represented by ca 300,000 species in about 400 families. Like all of Life, including ourselves, they have had their own history and gone through many evolutionary stages before they arrived at their current forms. The origin of Angiospermae ( owering plants) has been the subject of much dispute because this is a key event in the history of life, and has a far-reaching in uence on our understanding of relationships among seed plants as a whole as well as within the angiosperms. Until recently most of palae- otanists recognized angiosperms only from the Cretaceous and younger strata. This contradicts the results of molecular analyses. I have been working on Mesozoic fossil plants for the past two decades, during which time I have studied a number of fossil plants. Some of these fossil plants have been published as Jurassic angiosperms, and, unsurprisingly, many questions and doubts have been raised about them. These questions need to be addressed se- ously and journal papers do not provide suf cient space to compare and relate these early angiosperms. In this book these pioneer angiosperms are documented in detail, sometimes with new specimens not studied before. Also, I propose a de nition of angiosperms that could be adopted in palaeobotany. My aim is to improve clarity and objectivity of judgment about what constitutes a fossil angiosperm.

Paleontologists just recently opened their eyes to the wealth of fossil documents relevant to plant – arthropod interaction and are busy now accumulating raw data. Perhaps the richest regional collection of interaction traces came from the mid-Cretaceous deposits of the Negev Desert, Israel, encompassing the time interval of the rise and basal radiation of angiosperms – the flowering plants. The arthropods (insects and mites) inserting their eggs in the leaves and making leaf mines and galls were discovering new possibilities for endophytic life that the flowering plants provided. Their morphological disparity suggests a diversification race, in which the angiosperms failed to override their leaf parasites. Only a small fraction of insect diversity is represented by body fossils that belong to one extinct and nine extant families of beetles and cockroaches mostly. Because similar structures are produced on leaves by parasitic arthropods of different systematic alliances, a purely morphological classification is worked out for the trace fossils, with but tentative assignments to natural taxa, referring to distinct types of parasitic behavior. It is the Evolution of behavior that is documented by the trace fossils. The body fossils and parasitic traces represent morphologies and behavioral traits fairly advanced for their geological age. The expression, abundance, co-occurrence, and host specialization of parasitic structures, as well as the marks of predation on mines and galls betray regulatory mechanisms of plant – arthropod interaction, analyzed in the broad context of ecosystem evolution, paleogeography and climate change.

Palaeobiology: A Synthesis was widely acclaimed both for its content and production quality. Ten years on, Derek Briggs and Peter Crowther have once again brought together over 150 leading authorities from around the world to produce Palaeobiology II. Using the same successful formula, the content is arranged as a series of concise articles, taking a thematic approach to the subject, rather than treating the various fossil groups systematically. This entirely new book, with its diversity of new topics and over 100 new contributors, reflects the exciting developments in the field, including accounts of spectacular newly discovered fossils, and embraces data from other disciplines such as astrobiology, geochemistry and genetics. Palaeobiology II will be an invaluable resource, not only for palaeontologists, but also for students and researchers in other branches of the earth and life sciences. Written by an international team of recognised authorities in the field. Content is concise but informative. Demonstrates how palaeobiological studies are at the heart of a range of scientific themes.
