Book excerpt: Excerpt from Systematics and Morphology of American Mosasaurs (Reptilia, Sauria) Surely as much has been written about mosasaurs as any other group of fossil reptiles of comparable abundance and diversity. The division of the family Mosasauridae into three major subfamilies and the close relationship to varanid lizards has been generally recognized for more than fifty years. Yet on a generic and specific level their taxonomy has been so confused that even after a careful survey of the literature it was usually impossible to be sure of the correct binomial to use in identifying a given specimen. As a consequence modern verte brate paleontologists have by and large tended to ignore mosasaurs as a subject of research.

Available in PDF, EPUB and Kindle. Book excerpt: Squamata (amphisbaenians, "lizards, " mosasaurs, and snakes) is an extremely diverse clade with a rich fossil record. There is little consensus about the interrelationships of the major squamate clades (i.e., Iguania, Gekkota, Scincomorpha, Anguimorpha, Amphisbaenia, and Serpentes), or even the membership of some of these clades. Morphology-based cladistic analyses typically agree only that the major dichotomy in extant squamates is between Iguania and all other taxa. The phylogenetic placement of Amphisbaenia and Serpentes is particularly problematic. Incomplete taxon sampling is likely a major contributing factor to the absence of a consensus about squamate interrelationships. This study examines squamate relationships using 222 ingroup taxa scored for 363 morphological characters. Analysis of these data recovered 2,213 equally short trees with a length of 3,273 steps and a retention index of 0.7164. The results confirm the monophyly of the clades Scleroglossa (extant squamates exclusive of Iguania), Gekkota, Scincomorpha, Lacertoidea, Scincoidea, Anguimorpha, Carusioidea, Platynota, and Varanoidea. Novel results include the identification of a clade containing Scincidae sensu lato, Dibamidae, Amphisbaenia, and Serpentes; identification of a Mesozoic clade containing Bainguis, Eoxanta lacertifrons, Globaura venusta, and Myrmecodaptria; and identification of Dalinghosaurus as a basal shinisaur. A new taxonomic scheme is outlined. The names Iguanomorpha, Scincogekkonomorpha, Evansauria, and Mosasauriformes are applied to the stem-based groups including Iguania, Scleroglossa, Autarchoglossa, and Mosasauria, respectively. The importance of strict rigidity within taxonomy is questioned; taxonomy is most useful as a tool for communication about organisms or groups of organisms.

Download or read book Herpetological Osteopathology written by Bruce M. Rothschild and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.
Download or read book Dinosaurs and Other Extinct Saurians written by Richard Moody and published by Geological Society of London. This book was released on 2010 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of dinosaurs and other large extinct saurians - a term under which the Victorians commonly lumped ichthyosaurs, plesiosaurs, pterosaurs and their kin - makes exciting reading and has caught the attention of palaeontologists, historians of science and the general public alike. The papers in this collection go beyond the familiar tales about famous fossil hunters and focus on relatively little-known episodes in the discovery and interpretation (from both a scientific and an artistic point of view) of dinosaurs and other inhabitants of the Mesozoic world. They cover a long time span, from the beginnings of modern scientific palaeontology in the 1700s to the present, and deal with many parts of the world, from the Yorkshire coast to Central India, from Bavaria to the Sahara. The characters in these stories include professional palaeontologists and geologists (some of them well-known, others quite obscure), explorers, amateur fossil collectors, and artists, linked together by their interest in Mesozoic creatures.

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

Book excerpt: In the days when dinosaurs dominated the earth, their marine counterparts - every bit as big and ferocious - reigned supreme in prehistoric seas. In this book, Richard Ellis takes us back to the Mesozoic era to resurrect the fascinating lives of these giant seagoing reptiles. fierce predators, speculates on their habits, and tells how they eventually became extinct - or did they? He traces the 200-million-year history of the great ichthyosaurs, plesiosaurs and mosasaurs who swam the ancient oceans - and who may, according to some, still frequent the likes of Loch Ness. animal that looked like a crocodile crossed with a shark the size of a small yacht. With its impossibly long neck, Plesiosaurus conybeari has been compared to a giant snake threaded through the body of a turtle. At a length of nearly 60 feet, Mosasaurus hoffmanni boasted powerful jaws that could crunch up even the hardest-shelled giant sea turtle. And Kronosaurus queenslandicus, perhaps the most formidable of the lot, had a skull nine feet long - more than twice that of Tyrannosaurus rex - with teeth to match. reconstruct their lives and habitats. Their fossils have been found all over the world - in Europe, Australia, Japan and even Kansas - in lands that once lay on the floors of Jurassic and Triassic seas. Along the way, the book also provides intriguing insights into and entertaining tales about the work, discoveries and competing theories that compose the world of vertebrate paleontology. The text is also accompanied by Ellis' own illustrations of how these creatures probably appeared and, through these likenesses, we are invited to speculate on their locomotion, their predatory habits and their lifestyles.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The evolution of vertebrate hearing is of considerable interest in the hearing community. However, there has never been a volume that has focused on the paleontological evidence for the evolution of hearing and the ear, especially from the perspective of some of the leading paleontologists and evolutionary biologists in the world. Thus, this volume is totally unique, and takes a perspective that has never been taken before. It brings to the fore some of the most recent discoveries among fossil taxa, which have demonstrated the sort of detailed information that can be derived from the fossil record, illuminating the evolutionary pathways this sensory system has taken and the diversity it had achieved.
