Book Description
This book provides a comprehensive synthesis of the range of biological information that can be retrieved from the fossilised skeletons of echinoids. The first half consists of a detailed explanation of the functional significance of skeletal structures and the inferences to be drawn from them about the living animals. This is followed by a discussion of the important evolutionary changes that have taken place and why they may have occurred. Finally, there is a section on how echinoids relate to other echinoderm groups.

Book Description
The dominant faunal elements in shallow Paleozoic oceans, echinoderms are important to understanding these marine ecosystems. Echinoderms (which include such animals as sea stars, crinoids or sea lilies, sea urchins, sand dollars, and sea cucumbers) have left a rich and, for science, extremely useful fossil record. For various reasons, they provide the ideal source for answers to the questions that will help us develop a more complete understanding of global environmental and biodiversity changes. This volume highlights the modern study of fossil echinoderms and is organized into five parts: echinoderm paleoecology, functional morphology, and paleoecology; evolutionary paleoecology; morphology for refined phylogenetic studies; innovative applications of data encoded in echinoderms; and information on new crinoid data sets.

Book Description
This book provides practical morphological information, together with detailed illustrations and concise texts explaining each entry. The book details the morphological characters of each organism, providing fundamental information for palaeontologists and palaeobiologists alike. Each chapter starts with a brief introduction and goes on to describe the organism’s morphology in detail, followed by a brief note on classification and lastly illustrated examples of stratigraphically important organisms through time along with their major distinguishing characters. The book includes over 3000 clearly labelled, hand-drawn and classroom-friendly illustrations of over 1200 species.

Book Description
The study of echinoid evolution, diversity, and ecology has always suffered from the fact that they are represented by taxa showing widely differing architectural designs of their multi-plated skeletons, inhabiting a large range of marine paleoenvironments, which result in highly varying taphonomic biases dictating their presence and recognition. This Element addresses the taphonomy of echinoids and includes: a general introduction to the morphological features of echinoids that play a role in their preservation; a review of processes which play an important role in the differential preservation of both regular and irregular echinoids including predation and transport; a summary of taphonomic pathways included in actualistic studies for recent sea urchins and then reconstructed for fossil taxa; and finally, a case study of the variation of echinoid taphonomy across a shelf gradient using the rich Miocene echinoid fauna of Sardinia.

Book Description
Sea urchins are a major component of the world ocean. They are important ecologically and often greatly affect marine communities. They have an excellent fossil record and consequently are of interest to paleontologists. Research has increased in recent years stimulated first by a recognition of their ecological importance and then because of their economic importance. Scientists around the world are actively investigating their potential for aquaculture. This book is designed to provide a broad understanding of the biology and ecology of sea urchins. Synthetic chapters consider biology of sea urchins as a whole to give a broad view. The topics of these chapters include reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids, disease and nutrition. Subsequent chapters consider the ecology of individual species that are of major importance ecologically and economically. These include species from Japan, New Zealand, Australia, Europe, North America, South America and Africa. * First comprehensive book devoted to the biology and ecology of sea urchins * NEW chapter on Nutrition of Sea Urchins and Ecology of Diadema * Brand NEW illustrations * Hot NEW topic: Immunology of the Sea Urchin * Chapters written by internationally recognized experts * Each chapter revised and updated from the first edition * Biological chapters include reproduction, endocrinology, carotenoids and disease * Ecological chapters include species of major economic interest for fisheries and aquaculture

Book Description
This book is the second volume of two books about sea urchins (echinoids) since 1953 (Th. Mortensen). The detailed and coloured illustrated descriptions enable the reader to identify all species living today in our oceans. Recent scientific searchings are included. Volume II. describes the Irregularia with bilateral symmetry, including the well known "sand dollars" and "heart urchins", living mostly more or less deeply burrowed in the substrat.

Book Description
This book presents a comprehensive overview of the science of the history of life. Paleobiologists bring many analytical tools to bear in interpreting the fossil record and the book introduces the latest techniques, from multivariate investigations of biogeography and biostratigraphy to engineering analysis of dinosaur skulls, and from homeobox genes to cladistics. All the well-known fossil groups are included, including microfossils and invertebrates, but an important feature is the thorough coverage of plants, vertebrates and trace fossils together with discussion of the origins of both life and the metazoans. All key related subjects are introduced, such as systematics, ecology, evolution and development, stratigraphy and their roles in understanding where life came from and how it evolved and diversified. Unique features of the book are the numerous case studies from current research that lead students to the primary literature, analytical and mathematical explanations and tools, together with associated problem sets and practical schedules for instructors and students. New to this edition The text and figures have been updated throughout to reflect current opinion on all aspects New case studies illustrate the chapters, drawn from a broad distribution internationally Chapters on Macroevolution, Form and Function, Mass extinctions, Origin of Life, and Origin of Metazoans have been entirely rewritten to reflect substantial advances in these topics There is a new focus on careers in paleobiology

Book Description
The first introductory palaeontology text which demonstrates the importance of selected fossil groups in geological and biological studies, particularly in understanding evolutionary patterns, palaeoenvironmental analysis, and stratigraphy. Part one explores several key concepts, such as the processes of fossil preservation, the determination of evolutionary patterns, and use of fossils and statigraphical tools. Part two introduces the main fossil groups of value in these applied fields. Part three concentrates on the examination of important case histories which demonstrate the use of fossils in diverse practical examples. Evolutionary studies, palaeoenvironmental analysis, and stratigraphical applications are documented using up-to-date examples supported by overviews of the principles.
