Download or read book The Evolution of Mammalian Characters written by D. M. Kermack and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is not intended to give a full and comprehensive account of the Mesozoic mammals, and nor is it intended as a handbook for research workers studying pre-Tertiary mammals. Our intention is to give an account of the origin and evolution of certain of the characters of the Mammalia. We have tried to portray the fossils we describe as the living animals they once were, not as dead bones. Our account ends with the end of the Lower Cretaceous, since by that time the major characters of the mammals had become established. There exist a number of characters which, at the present day, are confined to the Mammalia. These include: (1) a jaw articulation formed by the squamosal and the dentary; (2) a chain of three bones, malleus, incus and stapes connecting the tympanic membrane to the inner ear; (3) the presence of hair or fur; (4) the presence of milk-glands in the female; (5) the left aortic arch is the systemic arch; (6) the phalangeal formula in both manus and pes is 2.3.3.3.3; (7) some of the teeth have more than one root. Of these characters (1) or (2) are sufficient by themselves to define a mammal; characters (6) and (7) are known to have been already in existence in some of the mammal-like reptiles - the ancestors of the mammals.
Download or read book In Pursuit of Early Mammals written by Zofia Kielan-Jaworowska and published by Indiana University Press. This book was released on 2013-07-12 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Mesozoic mammal fossils are the focus of this fascinating book, which reviews both the fossils themselves and the history of their discovery.” —Choice In Pursuit of Early Mammals presents the history of the mammals that lived during the Mesozoic era, the time when dinosaurs ruled the Earth, and describes their origins, anatomy, systematics, paleobiology, and distribution. It also tells the story of the author, a world-renowned specialist on these animals, and the other prominent paleontologists who have studied them. Zofia Kielan-Jaworowska was the first woman to lead large-scale paleontological expeditions, including eight to the Gobi Desert in Mongolia, which brought back important collections of dinosaur, early mammal, and other fossils. She shares the difficulties and pleasures encountered in finding rare fossils and describes the changing views on early mammals made possible by these discoveries. “A thorough review of the current state of early mammalian paleontology presented through the unique historical filter of someone who was at the foremost of the field for over half a century.” —The Quarterly Review of Biology “Whether she’s talking about how mammals evolved their distinctive ear bones, or how she built a cabin out of plywood during a particularly cold field season in the Gobi, you know that a remarkable, passionate person is telling a story of science and adventure in her own words.” —Priscum “A fascinating window into the development of the field . . . The perspective of an individual at the center of these developments is captivating, informative, and has never before been published.” —Gregory P. Wilson, University of Washington

Download or read book Mammalian Evolution Diversity and Systematics written by Frank Zachos and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-10-22 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are nearly 6,000 mammalian species, among them our own. Research on our evolutionary cousins has a long history, but the last 20 years have seen particularly rapid progress in disentangling the interrelationships and evolutionary history of mammals. The present volume combines up-to-date reviews on mammalian phylogenetics with paleontological, taxonomic and evolutionary chapters and also summarizes the historical development of our insights in mammalian relationships, and thus our own place in the Tree of Life. Our book places the present biodiversity crisis in context, with one in four mammal species threatened by extinction, and reviews the distribution and conservation of mammalian diversity across the globe. This volume is the introductory tome to the new Mammalia series of the Handbook of Zoology and will be essential reading for mammalogists, zoologists and conservationists alike.

Available in PDF, EPUB and Kindle. Book excerpt: Few aspects of American military history have been as vigorously debated as Harry Truman's decision to use atomic bombs against Japan. In this carefully crafted volume, Michael Kort describes the wartime circumstances and thinking that form the context for the decision to use these weapons, surveys the major debates related to that decision, and provides a comprehensive collection of key primary source documents that illuminate the behavior of the United States and Japan during the closing days of World War II. Kort opens with a summary of the debate over Hiroshima as it has evolved since 1945. He then provides a historical overview of thye events in question, beginning with the decision and program to build the atomic bomb. Detailing the sequence of events leading to Japan's surrender, he revisits the decisive battles of the Pacific War and the motivations of American and Japanese leaders. Finally, Kort examines ten key issues in the discussion of Hiroshima and guides readers to relevant primary source documents, scholarly books, and articles.

Download or read book Beast Companions written by John Foster and published by Indiana University Press. This book was released on 2024 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their fame and reputation, dinosaurs represent only half the story of the Mesozoic Era. In Beast Companions: The Unsung Animals of the Dinosaurs' World, paleontologist John Foster explores the often-overlooked animals that coexisted with them. These ancient species, often equally remarkable as their dinosaur neighbors, can provide valuable insights into the biotic history of our planet. In some cases, these animals reveal just as much, if not more, about the extinct ecosystems of the time as the dinosaurs themselves. By drawing on a wealth of current and past discoveries, Foster embarks on a sweeping journey across 164 million years to visit the beast companions of the dinosaurs. Along the way, he examines fish, insects, the first frogs and salamanders, turtles, snakes and lizards, marine reptiles, crocodiles, pterosaurs, birds, mammals, and other animals of the Mesozoic Era. Beast Companions is a groundbreaking exploration of the story of these contemporaries of the dinosaurs that set the modern world in motion more than 200 million years ago
Download or read book In the Shadow of the Dinosaurs written by Nicholas C. Fraser and published by Cambridge University Press. This book was released on 1997-08-28 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The early Mesozoic period was a critical period in the evolution of life on land when most of todays major groups of terrestrial vertebrates arose and dinosaurs and pterosaurs rose to prominence. In recent years this period has received a great deal of attention from palaeontologists, and it is now felt that the small vertebrates which lived in the shadows of the first dinosaurs tell us a great deal about the evolution of modern terrestrial ecosystems. This book is an attempt to collate all the information on the small vertebrates and features contributions by experts with international reputations in their fields. There are chapters on the taxonomy and phylogeny of the key vertebrate groups followed by a section dealing with the most significant fossiliferous assemblages worldwide. The final section looks at how faunal turnover at this time is measured and examines the possibility of mass extinctions.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents perspectives on the past and present state of the understanding of snake origins. It reviews and critiques data and ideas from paleontology and neontology (herpetology), as well as ideas from morphological and molecular phylogenetics. The author reviews the anatomy and morphology of extant snakes. Methods are also critiqued, including those empirical and theoretical methods employed to hypothesize ancestral ecologies for snakes. The modern debate on squamate phylogeny and snake ingroup phylogeny using molecules and morphology is examined critically to provide insights on origins and evolution. Key Features Important major evolutionary transformation in vertebrate evolution Continuing historical debate in vertebrate paleontology Of wide interest to a core audience of paleontologists, herpetologists, and morphologists Author acknowledged as prominent contributor to debate over snake origins Based on remarkable well preserved fossil specimens

Download or read book Jurassic West Second Edition written by John Foster and published by Indiana University Press. This book was released on 2020-10-20 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: The famous bone beds of the Morrison Formation, formed one hundred and fifty million years ago and running from Wyoming down through the red rock region of the American Southwest, have yielded one of the most complete pictures of any ancient vertebrate ecosystem in the world. Jurassic West, Second Edition tells the story of the life of this ancient world as scientists have so far been able to reconstruct it. Aimed at the general reader, Jurassic West, Second Edition recounts the discovery of many important Late Jurassic dinosaurs such as Apatosaurus, Allosaurus, and Stegosaurus. But dinosaurs compose barely a third of the more than 90 types of vertebrates known from the formation, which include crocodiles and turtles, frogs and salamanders, dinosaurs and mammals, clams and snails, and ginkgoes, ferns, and conifers. Featuring nearly all new illustrations, the second edition of this classic work includes new taxa named since 2007, updates to the naming and classifications of some old taxa, and expanded sections on numerous aspects of Morrison Formation paleontology and geology.
