Book Description
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.

Book Description
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.

Book Description
This volume delves into a spectrum of theoretical as well as applied aspects of high-resolution stratigraphic approaches in paleontology. It explores how increasingly detailed knowledge of the fossil record can enhance our understanding of the evolution of life on Earth and also allows geoscientists to address a broad range of important evolutionary and environmental questions in this arena. A 'zipped' version of the program CONOP9 2007 along with read-me files, sample files, and other documentation are available via a web site (see below). An earlier version of CONOP9 was initially supplied with 'High-Resolution Approaches in Stratigraphic Paleontology' (PJ Harries, editor) and described in Chapter 13 of that volume. This is an updated version of the program, and the documentation supplied with this version supersedes the information supplied in that chapter.

Book Description
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.
