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.

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.
Taphonomy

This book was released on 1999-10-28. Taphonomy available in PDF, EPUB and Kindle. Taphonomy: A Process Approach is the first book to review the entire field of taphonomy, or the science of fossil preservation. It describes the formation of animal and plant fossils in marine and terrestrial settings and how this affects deciphering the ecology and extinction of past lifeforms and the environments in which they lived. The volume emphasises a process approach to taphonomy and reviews the taphonomic behaviour of all important taxa, plant and animal. It will be useful to anyone interested in the preservation of fossils and the formation of fossil assemblages, but it is aimed primarily at advanced students and professionals working in paleontology, stratigraphy, sedimentology, climate modeling and biogeochemistry.

Download and read online ebook Molecular Paleobiology of the Echinoderm Skeleton write by Jeffrey R. Thompson. This book was released on 2022-12-01. Molecular Paleobiology of the Echinoderm Skeleton available in PDF, EPUB and Kindle. The echinoderms are an ideal group to understand evolution from a holistic, interdisciplinary framework. The genetic regulatory networks underpinning development in echinoderms are some of the best known for any model group. Additionally, the echinoderms have an excellent fossil record, elucidating in in detail the evolutionary changes underpinning morphological evolution. In this Element, the echinoderms are discussed as a model group for molecular palaeobiological studies, integrating what is known of their development, genomes, and fossil record. Together, these insights shed light on the molecular and morphological evolution underpinning the vast biodiversity of echinoderms, and the animal kingdom more generally.

Download and read online ebook A Review of Blastozoan Echinoderm Respiratory Structures write by Sarah L. Sheffield. This book was released on 2022-12-31. A Review of Blastozoan Echinoderm Respiratory Structures available in PDF, EPUB and Kindle. Echinoderms have evolved diverse and disparate morphologies throughout the Phanerozoic. Among them, blastozoans, an extinct group of echinoderms that were an important component of Paleozoic marine ecosystems, are primarily subdivided into groups based on the morphology of respiratory structures. However, systematic and phylogenetic research from the past few decades have shown that respiratory structures in blastozoans are not group-defining and they have re-evolved throughout echinoderm evolution. This Element provides a review of the research involving blastozoan respiratory structures, along with research concerning the morphology, paleoecology, and ontogeny of each of the major groupings of blastozoans as it relates to their corresponding respiratory structures. Areas of future research in these groups are also highlighted.
