Book excerpt: Seventy million years ago in what would become North America, a monstrous thirty-five-foot-long Cretaceous crocodile lurked on a marshy riverbank. Springing suddenly, its huge jaws trapped and crushed a juvenile hadrosaur. Today, the remains of that ancient crocodile are being painstakingly reconstructed in Colorado, where naturalist Zach Fitzner continues his life-long fascination with this amazing animal family. In Tears for Crocodilia: Evolution, Ecology, and the Disappearance of One of the World's Most Ancient Animals, Fitzner tracks the evolution of crocodilians from prehistoric predators to modern endangered wildlife, using his own experiences with these reptiles as a lens to understanding wildlife conservation and our relationship with the natural world. Traveling the world to interact with crocodiles, from observing alligators in a wildlife refuge in Texas and paddling a canoe in the Everglades searching for crocodiles to trekking the jungles in Nepal to find endangered gharials, the author expresses a wonder in exploring these diverse ecosystems, making a connection between crocodilians and the lands they live in. As the story follows crocodilians, it also illuminates their often complicated relationship with humans, from crocodile cults in ancient Egypt to American alligators living on golf courses. Fitzner also closely examines the dark side of this relationship, including habitat destruction and poaching as well as the mechanistic view of traditional conservation that turns these magnificent animals into agricultural products. Tears for Crocodilia delves deeply into issues of wildlife conservation, ethics, and how we can coexist with other creatures. It is also a tribute to a magnificent group of animals, survivors from the age of dinosaurs.

This book was released on 2003-08-29 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most geologically complex and diverse states, California spent much of the age of dinosaurs under water. While most of the fossils found in the state are those of reptiles that lived in the sea (thalattosaurs, ichthyosaurs, mosasaurs, plesiosaurs, and turtles), some are those of birds and pterosaurs that soared above it. Other fossils come from terrestrial animals that died and were washed into the ocean. These include turtles, crocodiles, lizards, and dinosaurs such as armored ankylosaurs, duck-billed hadrosaurs, and a variety of carnivorous dinosaurs. Richard Hilton is the first to tell the unsung 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. Vibrantly 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. Hilton 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. Dinosaurs and Other Mesozoic Reptiles of California takes this legacy one step further by documenting information about the fossils and their finders in accessible prose and vivid artistic renderings, creating a valuable contribution to our understanding of California’s prehistoric past.

Download or read book Biology and Evolution of Crocodylians written by Gordon Grigg and published by CSIRO PUBLISHING. This book was released on 2015-01-15 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology and Evolution of Crocodylians is a comprehensive review of current knowledge about the world's largest and most famous living reptiles. Gordon Grigg's authoritative and accessible text and David Kirshner's stunning interpretive artwork and colour photographs combine expertly in this contemporary celebration of crocodiles, alligators, caimans and gharials. This book showcases the skills and capabilities that allow crocodylians to live how and where they do. It covers the biology and ecology of the extant species, conservation issues, crocodylian–human interaction and the evolutionary history of the group, and includes a vast amount of new information; 25 per cent of 1100 cited publications have appeared since 2007. Richly illustrated with more than 500 colour photographs and black and white illustrations, this book will be a benchmark reference work for crocodylian biologists, herpetologists and vertebrate biologists for years to come.

Download or read book Hyman s Comparative Vertebrate Anatomy written by Libbie Henrietta Hyman and published by University of Chicago Press. This book was released on 1992-09-15 with total page 806 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book, now in its third edition, is to introduce the morphology of vertebrates in a context that emphasizes a comparison of structire and of the function of structural units. The comparative method involves the analysis of the history of structure in both developmental and evolutionary frameworks. The nature of adaptation is the key to this analysis. Adaptation of a species to its environment, as revealed by its structure, function, and reproductive success, is the product of mutation and natural selection–the process of evolution. The evolution of structure and function, then, is the theme of this book which presents, system by system, the evolution of structure and function of vertebrates. Each chapter presents the major evolutionary trends of an organ system, with instructions for laboratory exploration of these trends included so the student can integrate concept with example.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph has attempted to bring together morphological and physiological studies of reptilian lungs, to analyze the nature of the resulting correlations, and to risk some speculations regarding the evolution of reptilian lung structure. Central to this work is the morphometric evaluation of the lungs in two species of lizard: "the teju (Tupinambis nigropunctatus Spix) and the savanna monitor (Varanus exanthema ticus [Bosc]) which is presented here for the first time. These two species are similar in body form, and both are diurnally active predators, but their lungs are of basic ally different structural types. The teju possesses relatively small, single-chambered (unicameral) lungs in which the homeycomb-like (faveolar) parenchyma is more or less evenly distributed along their length. In the monitor the lungs are large and many-chambered (multicameral), the individual chambers connecting to an unbranched, intrapulmonary bronchus. The parenchyma is in the form of shallow cubicles (ediculae), which are elaborated on the intercameral septa. The parenchyma is heterogeneously distributed within the lungs, tending to be most concentrated near the intrapulmonary bronchus and the middle third of the lung length. The ventral and caudal portions of these lungs are thin-walled and highly flexible. In both species those portions of the lungs which are most exposed to air convection possess dense capillary nets which almost completely cover both sides of the parenchymal partitions. In more distal regions of the parenchy ma or of the lung, the intercapillary spaces become larger, creating a pseudo-single capillary net.
