The toxonomic importance and paleobiologic significance of such morphological features as phragmocone cross section, sutural configuration, apical angle, ornament, protoconch morphology, cameral deposits, septal necks, siphuncle position, wrinkle-layer (runzelschict), cameral ratio, septal orientation, color patterns, and abnormal or pathologic specimens are discussed.

Cephalopods Present and Past: New Insights and Fresh Perspectives

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

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.

Advancing Research on Living and Fossil Cephalopods

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.
