Documents the early history of paleontology and the role played by ammonoids Describes the basic anatomy of a diverse and long persisting lineage Summarizes the classification and diversity of ammonoids Lavishly illustrated with beautiful reconstructions Highlights recent findings and outstanding controversies

Ammonites are an extinct and charismatic lineage that persisted for over 300 million years. They were used, with other fossils, to corroborate the principle of faunal succession and launch the field of biostratigraphy. Despite intense research, many important questions remain unanswered. Furthermore, outdated hypotheses persist. Many new findings include a better understanding of their appearance in life, their locomotion, and their role in long gone ecosystems. And, of course, there are still controversies; e.g. why did shell complexity increase during evolutionary history. This richly illustrated book describes the full range of ammonoids and their fascinating evolutionary history.

​This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of new fossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.

Renowned researchers summarize the current knowledge on ammonoid paleobiology. The book begins with a description of the systematic position of the Ammonoidea within the Cephalopoda, providing the phylogenetic framework for the rest of the book. Following discussions include soft- and hard-part morphology of ammonoids, rate of growth and ontogeny, and taphonomy and ecology. Closing chapters explore the distribution of ammonoids in time and space as well as their extinction at the end of the Cretaceous. With its diverse viewpoints and new material, this resource will benefit researchers and graduate students in paleontology, marine biology, and evolutionary biology.

The beautiful spiral shells of these long-extinct marine invertebrates are among the most sought after and recognizable of fossils, yet little has been published about ammonites outside of geological journals. Neale Monks and Philip Palmer look at the latest ideas on ammonite biology and ecology to present this detailed picture of a once diverse and widespread group of animals. Though an ammonite looks like a nautilus, the animal inside the shell was most closely related to today's octopus, squid, and cuttlefish. The authors describe the evolution of ammonites and their relatives and explain how they created their shells and used them as flotation devices. All the major groups of ammonites are described and illustrated (as are many minor ones), and important material is included on anatomy, feeding, reproduction, and pathology. The 300-million-year existence of ammonites ended at around the same time that dinosaurs became extinct. Fortunately, ammonites were once so abundant that their fossilized shells can be readily found, and the authors provide a helpful guide to locating and collecting these unique fossils.

The ammonoids (ammonites and goniatites) are a fossil group of cephalopods that are of particular interest because of their rapid rates of evolution. In this volume, international experts on ammonoids are brought together to discuss evolutionary issues relating to this group. Special emphasis is given to the organic and environmental factors that may have influenced rates of speciation and extinction. This book should thus be of interest to palaeobiologists and evolutionary biologists generally as well as to palaeontologists who are specifically concerned with the ammonoids.
