Advancing Research on Living and Fossil Cephalopods
Author: Federico OlórizPublisher: Springer Science & Business Media
ISBN: 1461548373
Category : Science
Languages : en
Pages : 546
Book Description
Relying on the latest analytical techniques, this all-embracing new reference offers comprehensive coverage of the development, evolution, and morphology of both fossil and living cephalopods. In 34 in-depth chapters a group of 51 international neontologists and peleontologists offer and opverview of current methods, data, analyses, and interpretations, and posit suggestions for future research. With its unparalleled combination of first-rate contributions on living and fossil cephalopods, this book provides researchers and advanced students in paleontology, invertebrate zoology, evolutionary biology, and allied disciplines with a trove of recent data and authoritative interpretations that will immeasurably benefit their own studies.
Ammonoid Paleobiology: From anatomy to ecology
Author: Christian KlugPublisher: Springer
ISBN: 9401796300
Category : Science
Languages : en
Pages : 943
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.

Author: Cephalopods Present and Past: New Insights and Fresh Perspectives
Author: Neil H. LandmanPublisher: Springer Science & Business Media
ISBN: 1402064616
Category : Nature
Languages : en
Pages : 493
Book Description
This book brings together international scientists who focus on present-day and fossil cephalopods, ranging broadly from Paleozoic ammonoids to today's octopods. It covers systematics and evolution; hard- and soft part morphology; and ecology, biogeography, and taphonomy. The book also includes new evidence for the existence of an ink sac in fossil ammonoids and features the first record of an in-depth study of octopus ecology in Alaska.
Ammonoid Paleobiology
Author: Neil H. LandmanPublisher: Springer Science & Business Media
ISBN: 9780306452222
Category : Science
Languages : en
Pages : 890
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.
