Download or read book Handbook of Lizards written by Hobart Smith and published by Cornell University Press. This book was released on 2018-04-11 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most thorough treatment of lizards of the United States and Canada when first published in 1946, Handbook of Lizards has become a landmark among herpetologists and lizard specialists. Hobart M. Smith spent years compiling and organizing information on 136 species of lizards for this classic study. With more than 300 illustrations, including black-and-white photographs, labeled drawings, range maps, and illustrated keys, this volume serves as a still-relevant and convenient reference guide to the study of North American lizards. Darrel Frost, a prominent lizard specialist, provides a foreword for the 1995 paperback edition that underscores the work's relevance for herpetology today. In the first section, Smith covers in concise fashion the habits, life history, habitats, methods of collection and preservation, and structural features of lizards. The second section of the book considers each species under topics that are conveniently arranged for studying both living lizards and laboratory specimens: range, type, locality, size, color, scalation, recognition characters, habitat and habits, and references. Smith also discusses problems for further study and gives recommendations for special investigations of each species. The book concludes with an extensive bibliography.

Download or read book Miocene Modernization of the North American Lizard Fauna written by Simon George Scarpetta and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terrestrial ecosystems changed substantially during the Cenozoic era. The early Cenozoic was characterized by a warm and wet climate and ecosystems reminiscent of the modern tropics. Plant and animal communities similar to the modern biota were hypothesized to have appeared during the Miocene epoch. The phylogenetic, ecologic, and biogeographic assembly of the modern biota in North America and during the Miocene is well studied among fossil mammals and plants, but is not well documented in ectothermic vertebrates, such as lizards. I employed paleontological, biological, and geological data to address the formation of the modern lizard biota in North America, focusing on pleurodontan lizards (horned lizards, anoles, and relatives) and alligator lizards, which are prominent groups in modern ecosystems. My dissertation comprises three research foci: 1) Descriptions of fossil lizards, primarily from the Miocene but also from the Oligocene and Eocene, to evaluate paleodiversity, paleoecology, and paleobiogeography of focal lizard groups, 2) divergence time estimation using published genetic data and fossil calibrations to temporally constrain the evolution of focal lizard groups, and 3) exploration of fossil identification methodologies, especially fossil diagnoses made in the context of alternative phylogenetic hypotheses. I found one relatively modern lizard fauna from the middle Miocene of Wyoming that corroborates the records of terrestrial plants and mammals. However, I also described fossil occurrences that defy biogeographical (e.g., Abronia from the middle Miocene of California) and ecological (e.g., Uma from the late Miocene of California) expectations based on the biology of living lizards. The fields of historical biogeography and paleoecology draw heavily from the modern biota to make inferences into the past, but I suggest caution in that practice, because the distributions and ecological tolerances of organisms change through time. In the process of diagnosing and identifying a new fossil lizard (Kopidosaurus), I found that attention to phylogenetic hypotheses derived from molecular datasets altered the inferred phylogenetic position of the new taxon. Phylogenetic analyses are a popular avenue among paleontologists for fossil diagnosis, and neglecting alternative phylogenetic hypotheses can hinder fossil diagnosis and all downstream hypotheses that are contingent on accurate fossil diagnosis

Download or read book Mesozoic Stratigraphy of India written by Santanu Banerjee and published by Springer Nature. This book was released on 2021-08-02 with total page 727 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book envisages a multi-proxy approach using stable isotopes, geochemical proxies, magnetic susceptibility and associated biotic events for paleoclimatic and paleoenvironmental interpretations of the Mesozoic sedimentary record of India. Mesozoic rocks of India record abnormal sea level rise, greenhouse climate, intensified volcanism, hypoxia in seawater, extensive black shale deposition, and hydrocarbon occurrence. The Mesozoic has also witnessed mass extinction events, evolution of dinosaurs, and breakdown of the supercontinent Pangea and the formation of Gondwana. Although the Mesozoic geology of India has witnessed significant progress in the last century, literature survey reveals a huge gap in knowledge regarding sequence stratigraphy, chemostratigraphy and key geological events. A synthesis of sedimentological, paleontological and chemical data is included to presenting a comprehensive understanding of the Indian Mesozoic record to students, researchers and professionals.

Download or read book At the Top of the Grand Staircase written by Alan L. Titus and published by Indiana University Press. This book was released on 2013-10-09 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Grand Staircase-Escalante National Monument is the location of one of the best-known terrestrial records for the late Cretaceous. Prior fieldwork confirmed the richness of the area, but a major effort begun in the new century has documented over 2,000 new vertebrate fossil sites, provided new radiometric dates, and identified five new genera of ceratopsids, two new species of hadrosaur, a probable new genus of hypsilophodontid, new pachycephalosaurs and ankylosaurs, several kinds of theropods (including a new genus of oviraptor and a new tyrannosaur), plus the most complete specimen of a Late Cretaceous therizinosaur ever collected from North America, and much more. The research documented in this book is rewriting our understanding of Late Cretaceous paleobiogeography and dinosaur phyletics. At the Top of the Grand Staircase: The Late Cretaceous of Southern Utah is a major stepping stone toward a total synthesis of the ecology and evolution of the Late Cretaceous ecosystems of western North America.
