The expert guide to the evolution and fossil record of cephalopods In Paleobiology of Ammonoids and their Relatives , Dr. McGowan delivers an up-to-date and comprehensive exploration of the evolution and biology of cephalopods that is written for non-specialists and experts in invertebrate biology and paleobiology alike. The book bridges the biology-paleontology divide, challenging some established thinking about cephalopod evolution and highlighting new research methods and results. The author explores areas of controversy, as well as the focus of current research, as he discusses the contributions of cephalopod research to discoveries in macroevolution and paleobiology. The only text to cover both extant and extinct cephalopod groups, this book also offers: A thorough introduction to the major cephalopod groups, including their fossil record Comprehensive explorations of the hard and soft tissues of cephalopods, including internal and external shells, as well as cephalopod brains and sensory systems Detailed surveys of the growth and form of cephalopods, as well as their locomotion and feeding Insightful discussions of cephalopod reproduction and life history, phylogeny and classification, and cephalopod biogeography Written for students and researchers in cephalopod biology and paleobiology, Paleobiology of Ammonoids and their Relatives will also earn a place in the library of every ammonoid fossil collector.
