Book excerpt: A classic work from the Yale Peabody Museum of Natural History describing the mosasaurs, a group of large predatory marine lizards of the Mesozoic Mosasaurs have captured the imagination of readers everywhere interested in prehistoric life, and they remain a focus of paleontological study to this day. This edition of Dale Russell's Systematics and Morphology of American Mosasaurs presents the complete, classic text, generously illustrated with more than one hundred drawings and photographs, and includes a new foreword by vertebrate paleontologist Jacques A. Gauthier (Yale University and Yale Peabody Museum of Natural History).

Download or read book The Vertebrate Integument Volume 2 written by Theagarten Lingham-Soliar and published by Springer. This book was released on 2015-02-18 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emphasis in this volume is on the structure and functional design of the integument. The book starts with a brief introduction to some basic principles of physics (mechanics) including Newton’s Three Laws of Motion. These principles are subsequently used to interpret the problems animals encounter in motion. It is in only the last 40 or so years that we have begun to understand how important a role the integument plays in the locomotion of many marine vertebrates. This involves the crossed-fiber architecture, which was first discovered in a classic study on nemertean worms. As a design principle we see that the crossed-fiber architecture is ubiquitous in nature. Research on some of the most dynamic marine vertebrates of the oceans – tuna, dolphins and sharks, and the extinct Jurassic ichthyosaurs – shows precisely how the crossed-fiber architecture contributes to high-speed swimming and (in lamnid sharks) may even aid in energy conservation. However, this design principle is not restricted to animals in the marine biota but is also found as far afield as the dinosaurs and, most recently, has been revealed as a major part of the microstructure of the most complex derivative of the integument, the feather. We see that a variety of phylogenetically diverse vertebrates take to the air by using skin flaps to glide from tree to tree or to the ground, and present detailed descriptions of innovations developed in pursuit of improved gliding capabilities in both extinct and modern day gliders. But the vertebrate integument had even greater things in store, namely true or flapping flight. Pterosaurs were the first vertebrates to use the integument as a membrane in true flapping flight and these interesting extinct animals are discussed on the basis of past and cutting-edge research , most intriguingly with respect to the structure of the flight membrane. Bats, the only mammals that fly, also employ integumental flight membranes. Classic research on bat flight is reviewed and supplemented with the latest research, which shows the complexities of the wing beat cycle to be significantly different from that of birds, as revealed by particle image velocimetry. The book’s largest chapter is devoted to birds, given that they make up nearly half of the over 22,000 species of tetrapods. The flight apparatus of birds is unique in nature and is described in great detail, with innovative research highlighting the complexity of the flight structures, bird flight patterns, and behavior in a variety of species. This is complimented by new research on the brains of birds, which shows that they are more complex than previously thought. The feather made bird flight possible, and was itself made possible by β-keratin, contributing to what may be a unique biomechanical microstructure in nature, a topic discussed in some depth. A highly polarized subject concerns the origin of birds and of the feather. Alleged fossilized protofeathers (primal simple feathers) are considered on the basis of histological and taphonomic investigative studies in Chapter 6. Finally, in Chapter 7 we discuss the controversies associated with this field of research. Professor Theagarten Lingham-Soliar works at the Nelson Mandela Metropolitan University, Port Elizabeth and is an Honorary Professor of Life Sciences at the University of KwaZulu-Natal.

Available in PDF, EPUB and Kindle. Book excerpt: Vertebrate evolution has led to the convergent appearance of many groups of originally terrestrial animals that now live in the sea. Among these groups are familiar mammals like whales, dolphins, and seals. There are also reptilian lineages (like plesiosaurs, ichthyosaurs, mosasaurs, thalattosaurs, and others) that have become sea creatures. Most of these marine reptiles, often wrongly called "dinosaurs", are extinct. This edited book is devoted to these extinct groups of marine reptiles. These reptilian analogs represent useful models of the myriad adaptations that permit tetrapods to live in the ocean. - First book in more than 80 years devoted exclusively to fossil marine reptiles - Documents the most current research on extinct marine reptiles - Prepared by the world's most prominent experts in the field - Well illustrated

Available in PDF, EPUB and Kindle. Book excerpt: “Excellent . . . Those who are interested in vertebrate paleontology or in the scientific history of the American midwest should really get a copy.” —PalArch’s Journal of Vertebrate Paleontology Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later. Michael J. Everhart vividly captures the history of these startling finds over the decades and re-creates in unforgettable detail these animals from our distant past and the world in which they lived—above, within, and on the shores of America’s ancient inland sea. “Oceans of Kansas remains the best and only book of its type currently available. Everhart’s treatment of extinct marine reptiles synthesizes source materials far more readably than any other recent, nontechnical book-length study of the subject.” —Copeia “[The book] will be most useful to fossil collectors working in the local region and to historians of vertebrate paleontology . . . Recommended.” —Choice

This book was released on 2012-10-03 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This major study on heterodontosaurid dinosaurs is the first to review the taxonomy, morphology, functional anatomy, and phylogeny of this important early radiation of small-bodied herbivores. Heterodontosaurids persisted for approximately 100 My, from Late Triassic to Early Cretaceous time, during which they evolved some of the most sophisticated dentitions for processing plant materials. Some species required reevaluation to establish unequivocally their status as heterodontosaurids, such as Echinodon from rocks in southern England, one of the first and smallest dinosaurs ever described. Tianyulong from northern China is described in more detail in the study and is shown to have unusual skeletal proportions, including a relatively large skull and very short forelimb. A new taxon, Pegomastax africanus gen. n. sp. n., is described from southern Africa with a short parrot-shaped bill. Tooth replacement and tooth-to-tooth wear is more common than previously thought among heterodontosaurids, which the author argues are herbivores despite their prominent caniniform teeth. Heterodontosaurds appear to have split early in their history into a northern group with primitive, subtriangular crowns and a southern group with deeper crown proportions.
