The Karoo fossil record tells us much about the many animals that lived in what is now South Africa and include astonishingly detailed information on the origin of mammals, the early appearance of dinosaurs and the ancestors of living reptiles such as crocodiles.
Evolution of Fossil Ecosystems describes all of the main Fossil Lagerstätten (sites of exceptional fossil preservation) from around the world in a chronological order. It covers the history of research, stratigraphy and taphonomy, main faunal and floral elements, and the palaeoecology of each site and gives a comparison with coeval sites around the w
To many people, especially those driving along the N1 national road at high speeds, the Karoo represents nothing more than a monotonous, hot and arid landscape to be passed through as quickly as possible. But in this vast, open region, history is everywhere, if visitors would only look for it. And that is exactly the purpose of this book: to point out all the many places, buildings, objects and associated personalities of historical interest in the Karoo. The Karoo has been the world of travellers, writers, statesmen and scientists, figures as diverse as Olive Schreiner, Rudyard Kipling, Winston Churchill and Dr Chris Barnard. It has also been the scene of serious conflict, of which the many old British blockhouses, forts, grave sites and memorials dating from the Anglo-Boer War are vivid reminders; and it still boasts old examples of vernacular and industrial architecture, and engineering, in the form of corbelled houses, water mills and bridges. The Historical Karoo is ordered according to three main routes that people drive through the area. It provides short histories of the towns along the way, and points out the sites, buildings and other aspects of interest that can be found there. Enlivened by historical and current photographs and informative side panels, this book is a collector’s item.
The Karoo is big sky country; a land of vast open plains punctuated by flat-topped mountains, conical hills and secluded valleys, a land of scrubby bushes and hardy trees, where pioneers carved roads out of rock to set down roots in an unforgiving environment. Here dreams are born, legends are made, and outcasts find sanctuary. It is also an ancient place, whose story is revealed through geology, fossils and artefacts, and whose human lineage predates any written history. Today, the people who inhabit it must manifest the same fortitude that sustained those who left their footprints in the primieval mud. In Hidden Karoo you will find all this, and more. Through a series of superb photo-essays, this majestic place is revealed as a land where conservation and neglect are seldom far apart, where one town boasts splendidly restored buildings, while along a dusty back road lie forgotten villages waiting for ... something. Could it be a renewal, or a slow death? There’s nothing novel about the movement of people from country to city, and the Karoo mimics other parts of the world where rural areas become derelict as they are depopulated. Hidden Karoo presents a snapshot of the region as it is now, offering a glimpse into towns and villages, farmsteads and churches, important buildings and humble homes, all against a backdrop of awe-inspiring landscapes. Through words and pictures, it prompts us to consider what was, what is and, perhaps, what might be. One constant about the Karoo is change. A book can do no more than capture a moment in time or depict fragments of a place, but in doing so, it bears witness to the past and offers the hope that there may yet be a future for this unparalleled part of our country.
Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian. After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened. Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today. In a new preface, Douglas Erwin assesses developments in the field since the book's initial publication.
Leading artists, theorists, and writers exhume the dystopian and utopian futures contained within the present “I am the supercommunity, and you are only starting to recognize me. I grew out of something that used to be humanity. Some have compared me to angry crowds in public squares; others compare me to wind and atmosphere, or to software.” Invited to exhibit at the 56th Venice Biennale, e-flux journal produced a single issue over a four-month span, publishing an article a day both online and on site from Venice. In essays, poems, short stories, and plays, artists and theorists trace the negative collective that is the subject of contemporary life, in which art, the internet, and globalization have shed their utopian guises but persist as naked power, in the face of apocalyptic ecological disaster and against the claims of the social commons. “I convert care to cruelty, and cruelty back to care. I convert political desires to economic flows and data, and then I convert them back again. I convert revolutions to revelations. I don’t want security, I want to leave, and then disperse myself everywhere and all the time.”
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.
Whether you are a bird-watcher, an angler, a hiker, a diver, an environmentalist, or merely a weekend nature lover, this guide will provide hours of fascinating reading and be an invaluable reference for years to come.
A groundbreaking argument on how endothermy--arguably the most important innovation in vertebrate evolution--developed in birds and mammals "Vividly narrated and illustrated. . . . Provocative and fascinating for specialists and lay readers alike."--Southeastern Naturalist This pioneering work investigates why endothermy, or "warm-bloodedness," evolved in birds and mammals, despite its enormous energetic costs. Arguing that single-cause hypotheses to explain the origins of endothermy have stalled research since the 1970s, Barry Gordon Lovegrove advances a novel conceptual framework that considers multiple potential causes and integrates data from the southern as well as the northern hemisphere. Drawing on paleontological data; research on extant species in places like the Karoo, Namaqualand, Madagascar, and Borneo; and novel physiological models, Lovegrove builds a compelling new explanation for the evolution of endothermy. Vividly narrated and illustrated, this book stages a groundbreaking argument that should prove provocative and fascinating for specialists and lay readers alike.
