Download or read book Evolution of Dental Tissues and Paleobiology in Selachians written by Gilles Cuny and published by Elsevier. This book was released on 2018-02-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chondrichthyans possess unique anatomical features compared to other vertebrates, in particular a fully cartilaginous skeleton and a permanently renewed dentition. These characteristics make the fossilization of whole bodies difficult and consequently their fossil record consists mainly of a large number of isolated teeth. The study of their dentition is therefore of primary interest for our understanding of the evolution of this group. Beyond the dental morphology, the structure of the tissues composing the dentition has proved an important source of information, sometimes difficult to interpret, on the eating habits and the paleobiology of these animals. This book makes a thorough review of the existing theories in this field of research as well as introducing new elements from more recent studies. Through close reference to the fossil record of ancient selachians it examines what the study of dental tissue in cartilaginous fish can tell us about the evolution and the past biology of these animals, as well as what we can learn about the evolution of teeth themselves. Focuses on the evolution of the teeth microstructure of the cartilaginous fishes Offers a complete overview of the terminology used to describe fish tooth microstructures Offers an overview of convergent enameloid microstructures between actinopterygians (ray-finned fishes) and chondrichthyans to enable better understanding of the evolution of this kind of tissue Highlights the importance of isolated fossil teeth to understand the evolution of whole clades Discusses the use of isolated fossil teeth to understand the evolution of whole clades
Download or read book Biology of Sharks and Their Relatives Second Edition written by Jeffrey C. Carrier and published by CRC Press. This book was released on 2012-04-09 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtually every area of research associated with sharks and their relatives has been strongly impacted by the revolutionary growth in technology. The questions we can now ask are very different than those reported even two decades ago. Modern immunological and genetic techniques, satellite telemetry and archival tagging, modern phylogenetic analysis, GIS, and bomb dating, are just a few of the techniques and procedures that have become a part of our investigative lexicon. A modern synthesis of the biology of Chondrichthyans, Biology of Sharks and Their Relatives, Second Edition discusses significant advances in the development and application of new molecular techniques to the understanding of the phylogenetic relationships among and between these groups. The book considers the effect of global changes on the status of sharks and their relatives, and how advances in technology and analytical techniques have changed not only how we approach problem solving and scientific investigations, but how we formulate questions. The book also introduces applications of new and novel laboratory devices, techniques, and field instruments. This second edition of the award winning and groundbreaking original exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera, presents cohesive and integrated coverage of key topics and discusses technological advances used in modern shark research. Offering a well-rounded picture for students and researchers, and far above competitors in scope and research, this new volume holds a wealth of data on the current status of Chondrichthyan research and provides the basis and springboard for original research.

Download or read book Biological Materials of Marine Origin written by Hermann Ehrlich and published by Springer. This book was released on 2014-12-01 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second monograph by the author on biological materials of marine origin. The initial book is dedicated to the biological materials of marine invertebrates. This work is a source of modern knowledge on biomineralization, biomimetics and materials science with respect to marine vertebrates. For the first time in scientific literature the author gives the most coherent analysis of the nature, origin and evolution of biocomposites and biopolymers isolated from and observed in the broad variety of marine vertebrate organisms (fish, reptilian, birds and mammals) and within their unique hierarchically organized structural formations. There is a wealth of new and newly synthesized information, including dozens of previously unpublished images of unique marine creatures including extinct, extant and living taxa and their biocomposite-based structures from nano- to micro – and macroscale. This monograph reviews the most relevant advances in the marine biological materials research field, pointing out several approaches being introduced and explored by distinct modern laboratories.

Download or read book Early Vertebrates written by Philippe Janvier and published by Oxford University Press, USA. This book was released on 1996 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents current knowledge of the early vertebrates--mainly fish, but including some terrestrial creatures--which lived about 250 to 470 million years ago. The work focuses on anatomical and phylogenetic questions, but includes information on fossil discovery and preparation, as well as the analysis of the characteristics from which their relationships may be reconstructed. The author addresses both new and old problems in the evolution of certain anatomical details and deals briefly with the animals' way of life, extinction, and former distribution. The book is the first in its field to use a cladistic approach. For each major vertebrate group, the reader will find a diagram of relationships, or cladogram, with a selection of characters at each node, and a succinct phylogenetic classification.
