Book Description
Non-mammalian synapsids were the dominant terrestrial vertebrates from the Late Carboniferous to the Middle Triassic and play a key role in understanding the origin and evolution of mammals. Despite these facts and the outstanding fossil record of the group, early synapsids remain obscure. This book showcases the full breadth of contemporary research on non-mammalian synapsids, ranging from taxonomy and phylogenetics to functional morphology, biogeography, paleoecology, and patterns of diversity. It also underscores the importance and potential of studying non-mammalian synapsid paleobiology in its own right, not just in the context of mammalian evolution.​

Book Description
For most of us, the story of mammal evolution starts after the asteroid impact that killed the dinosaurs, but over the last 20 years scientists have uncovered new fossils and used new technologies that have upended this story. In Beasts Before Us, palaeontologist Elsa Panciroli charts the emergence of the mammal lineage, Synapsida, beginning at their murky split from the reptiles in the Carboniferous period, over three-hundred million years ago. They made the world theirs long before the rise of dinosaurs. Travelling forward into the Permian and then Triassic periods, we learn how our ancient mammal ancestors evolved from large hairy beasts with accelerating metabolisms to exploit miniaturisation, which was key to unlocking the traits that define mammals as we now know them. Elsa criss-crosses the globe to explore the sites where discoveries are being made and meet the people who make them. In Scotland, she traverses the desert dunes of prehistoric Moray, where quarry workers unearthed the footprints of Permian creatures from before the time of dinosaurs. In South Africa, she introduces us to animals, once called 'mammal-like reptiles', that gave scientists the first hints that our furry kin evolved from a lineage of egg-laying burrowers. In China, new, complete fossilised skeletons reveal mammals that were gliders, shovel-pawed Jurassic moles, and flat-tailed swimmers. This book radically reframes the narrative of our mammalian ancestors and provides a counterpoint to the stereotypes of mighty dinosaur overlords and cowering little mammals. It turns out the earliest mammals weren't just precursors, they were pioneers.

Book Description
Mammals are the dominant large animals of today, occurring in virtually every environment. This book is an account of the remarkable 320 million year long fossil record that documents their origin, their long spell as no more than small, nocturnal creatures, and their explosive radiation since the extinction of the dinosaurs 65 million years ago. Tom Kemp also unveils the exciting molecular evidence, which, coupled with important new fossils, is presently challenging current thinking on the interrelationships and historical biogeography of mammals. The Origin and Evolution of Mammals will be of interest to advanced undergraduate and graduate students as well as researchers in vertebrate palaeontology, biogeography, mammalian systematics and molecular taxonomy. It will also be welcomed by vertebrate fossil enthusiasts and evolutionary biologists of all levels with an interest in macroevolutionary problems.

Book Description
From a modest beginning in the form of a little shrew-like, nocturnal, insect eating ancestor that lived 200 million years ago, mammals evolved into the huge variety of different kinds of animals we see today. Many species are still small, and follow the lifestyle of the ancestor, but others have adapted to become large grazers and browsers, like the antelopes, cattle, rhinos, and elephants, or the lions, hyaenas, and wolves that prey upon them. Yet others evolved to be specialist termite eaters able to dig into the hardest mounds, or tunnel creating burrowers, and a few took to the skies as gliders and the bats. Many live partly in the water, such as otters, beavers, and hippos, while whales and dugongs remain permanently in the seas, incapable of ever emerging onto land. In this Very Short Introduction T. S. Kemp explains how it is a tenfold increase in metabolic rate - endothermy or "warm-bloodedness" - that lies behind the high levels of activity, and the relatively huge brain associated with complex, adaptable behaviour that epitomizes mammals. He describes the remarkable fossil record, revealing how and when the mammals gained their characteristics, and the tortuous course of their subsequent evolution, during which many bizarre forms such as sabre-toothed cats, and 30-tonne, 6-m high browsers arose and disappeared. Describing the wonderful adaptations that mammals evolved to suit their varied modes of life, he also looks at those of the mainly arboreal primates that culminated ultimately in Homo sapiens. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Description
This edited volume explores the various views on the origins of tetrapods—amphibians, reptiles, birds, and mammals—views that agree or differ depending in part on how certain fossil animals are classified and which methodology is used for classification. Eighteen chapters by an international group of paleontologists and neontologists here present current hypotheses, emphasizing the kinds of data needed to answer controversial questions, as well as the variety of solutions that emerge from diferent analyses of the same data set. The book is arranged in five sections, each of which contains an overview essay that either describes the development of various schools of thought regarding the origin of the tetrapod group in question or critically summarizes the arguments presented in the section. The first section addresses the origins of tetrapods as a group, focusing on lobe-finned fishes and early tetrapods. Next is a section dealing with amphbians, followed by one on reptiles. The fourth section concerns avian origins, and the final section treats the origins and early diversification of mammals. With an overall goal of stimulating critical evaluation by the reader rather than providing unequivocal answers, this volume will be of particaular interest to vertebrate paleontologists, evolutionary morphologists, and ichthyological, herpatological, avian, and mammalian systematists.

Book Description
The defining masterwork on the evolution of reptiles. Over 300 million years ago, an early land vertebrate developed an egg that contained the embryo in an amnion, allowing it to be deposited on land. This moment marked the first step in the fascinating and complex evolutionary journey of the reptiles. In The Rise of Reptiles, paleontologist Hans-Dieter Sues explores the diversity of reptilian lineages, discussing the relationships among turtles, crocodylians, lizards and snakes, and many extinct groups. Reflecting the tremendous advances in the study of reptilian diversity and phylogeny over recent decades, this book is the first detailed, contemporary synthesis of the evolutionary history of these remarkable animals. Reptiles have always confused taxonomists, who have endlessly debated and rewritten their classifications. In this book, Sues adopts an explicitly phylogenetic framework to sift through the evidence and discuss the origin and diversification of Reptilia in a way no one has before. He also examines the genealogical link between dinosaurs and birds and sheds new light on the Age of Reptiles, a period that saw the rise and fall of most dinosaurs. With this single meticulously researched volume, Sues paints a complete portrait of reptilian evolution. Numerous photographs of key specimens from around the world introduce readers to the reptilian fossil record, and color images of present-day reptiles illustrate their diversity. The extensive bibliography provides an invaluable guide for readers who are interested in exploring individual topics more deeply. Accurate, synthetic, and sweeping, The Rise of Reptiles is the definitive work on the subject.
