This book was released on 2016-12-22 with total page 258 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: "Inspired by the spectacular discoveries of the past two decades from the Age of Reptiles in China, Riddle of the Feathered Dragons explores how these miraculous fossils have transformed the contentious arena of bird and dinosaur evolution. Aside from being the most comprehensive discussion of these avian and associated discoveries, the author delves into the world of investigative journalism to expose the darker side of the world of fossil birds and dinosaurs. The book exposes the massive unfounded speculation that has characterized the field of vertebrate paleontology and published extensively in the world's most prestigious journals, including everything from supposed dinosaur protein to so-called feathered dinosaurs. The book questions the validity of the foundational tenets of the now "unquestionable orthodoxy" of bird and dinosaur evolution, including bird origins, feathered dinosaurs, flight origin from the ground-up and hot-blooded dinosaurs and their proteins. It exposes how speculation has gone far beyond the ability of the currently available evidence to yield answers. The author concludes that birds are best defined by a more traditional definition of the possession of feathers and avian flight architecture, that the so-called "feathered dinosaurs" are most likely derived avians, and that flight clearly originated from the trees-down, from ancestors that antedated the dinosaurs, rather than a direct linear descent"--

Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Paleontology is designed to address the shortage of general reference works on both vertebrate and invertebrate paleontology and to serve the needs of students and lay persons interested in the field. As the encyclopedia aims to provide basic information, the majority of the 350 entries are devoted to explanations of paleontological concepts and techniques, examinations of the evolutionary development of particular organisms and biological features, profiles of major discoveries, and biographies of leading scientists. Each entry includes an essay and a further reading list. An international team of 200 leading experts in the field has prepared the illustrations and the essays, which range from concise descriptions to comprehensive discussions.
Download or read book Regional Stratigraphy of North America written by W.J. Frazier and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: An early reviewer of this book stated that he had difficulty assessing its marketability because it "falls between the cracks" of geological literature. We have designed this book to meet a need of modem geology: namely, a single source providing both detailed and synoptic stratigraphy of the various regions of North America, through geological time. Shortly after beginning work on such a book, we realized why it had not yet been written: it required six years of effort, assimilation of an incredible amount of information, and two years' additional work to cut the volume down to publishable size. Further, by the time the final chapter was written, the fIrst few were already out of date. Nevertheless, the book lies in front of you. It is intended to serve several purposes. As a textbook, it will serve the following courses: • Regional stratigraphy • Sedimentary tectonics • Regional tectonics • Advanced historical geology • Survey-level paleontology Obviously, not all portions of the book are relevant to all of the above courses. We assume the reader will retain this book after the particular course is done, and will use it as a reference book. Hopefully, others will obtain the book solely for reference purposes. We believe it will be especially useful for the working geologist or academic geologist seeking generalized and some moderately detailed information about a region or geological time interval which is unfamiliar.

This book was released on 2003-08-29 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume tells the story of the dinosaurs and reptiles of land, sea, and sky that lived in California and Baja California during the Mesozoic era (245 million-65 million years ago), in addition to the history of their discovery. Illustrated with more than three hundred photographs, paintings, and drawings, this book provides geological and environmental details, describes the significance of the major fossils, and chronicles the adventures involved in the discovery, preparation, and publishing of the finds. The author also includes accounts of the scientists, teachers, students, ranchers, and weekend fossil hunters who endured (and continue to endure) harsh weather, fires, wild animals, and the usual challenges of fieldwork to collect fossil remains and make major discoveries. These enthusiasts managed to safeguard an abundance of fossil resources, some of which would otherwise have been destroyed by quarrying, paving, and housing developments.
