The evolution of high-crowned teeth, hypsodonty, is a defining characteristic of many terrestrial herbivores. To date, the most prominent focus in the study of the teeth of grazing herbivores has been co-evolution with grasses and grasslands. This book develops the idea further and looks at the myriad ways that soil can enter the diet. Madden then expands this analysis to examine the earth surface processes that mobilize sediment in the environment. The text delivers a global perspective on tooth wear and soil erosion, with examples from the islands of New Zealand to the South American Andes, highlighting how similar geological processes worldwide result in convergent evolution. The final chapter includes a review of elodonty in the fossil record and its environmental consequences. Offering new insights into geomorphology and adaptive and evolutionary morphology, this text will be of value to any researcher interested in the evolution of tooth size and shape.

Evolution of the horse has been an often-cited primary example of evolution, as well as one of the classic and important stories in paleontology for over a century and a half, due to their rich fossil record across 5 continents: North America, South America, Europe, Asia and Africa. The recent horse has served a profound role in human ancestry, including agriculture, commerce, sport, transport, warfare, and in prehistory, for the subsistence of humans. Many studies have examined the evolution of the Equidae and chronicled the striking changes in skulls, dentition, limbs, and body size which have long been perceived to be a response to environmental shifts through time. Most comprehensive studies heretofore have: (1) focused on the “Great Transformation”- changes that occurred in the early Miocene, (2) involved tracking long-term diversity or paleoecological trends on a single continent or within a geographical locality, or (3) concentrated on the 3-toed hipparions. The Plio–Pleistocene evolutionary stage of horse evolution is punctuated by the great climatic fluctuations of the Quaternary beginning 2.6 Ma which influenced Equus evolution, biogeographic dispersion and adaptation on a nearly global scale. The evolutionary biology of Equus evolution across its entire range remains relatively poorly understood and often highly controversial. Some of this lack of understanding is due to assumptions that have arisen because of the relatively derived craniodental and postcranial anatomy of Equus and its close relatives which has seemed to imply that that these forms occupied relatively homogenous and narrow dietary and locomotor niches - notions that have not been adequately addressed and rigorously tested. Other challenges have revolved around teasing apart environmentally-driven adaptation versus phylogenetically defined morphological change. Geochronologic age control of localities, geographic provinces and continents has improved, but in no way is absolute and can be reexamined in our proposed volume. Temporal resolution for paleodietary, paleohabitat and paleoecological interpretations are also challenging for understanding the evolution of Equus. Our proposed volume attempts to assemble a group of experts who will address multiple dimensions of Equus’ evolution in time and space.

A compilation of a wide range of topics discussed by world-renowned experts in the field of equine dentistry. The new edition of this popular resource represents a total revision of previous content and provides the reader with state-of-the-art knowledge of the field. Comprehensive and definitive, Equine Dentistry third edition retains the successful approach of extensive illustration and step-by-step guidance through oral and dental procedures. In addition, it includes many new figures, expanded text sections in key areas and brings to the team two new editors of international repute. Many new contributions from international experts are combined in this text to promote not only the care of horses in regards to oral and dental health but also the education of veterinary professionals in this rapidly developing area. Jack Easley is joined by James Schumacher and Padraic Dixon in the editorial team Seven new chapters reflect the major advances in dental anatomy and disease and also more general advances in analgesia and anesthesia, diagnostic imaging, and dental surgery The brand-new DVD provides visual as well as vocal guidance to techniques of equine dental examination and prophylactic treatment

This volume presents an array of different case studies which take as primary material data sourced from the NOW (‘New and Old Worlds’) database of fossil mammals. The NOW database was one of the very first large paleobiological databases, and since 1996 it has been expanded from including mainly Neogene European land mammals to cover the entire Cenozoic at a global scale. In the last two decades the number of works that are based in the use of huge databases to explore ecological and evolutionary questions has increased exponentially, and even though the importance of big data in paleobiological research has been outlined in selected chapters of general works, no volume has appeared before this one which solely focuses on the databases as a primary source in reconstructing the past. The purpose of this book is to provide an illustrative volume showing the importance of big data in paleobiological research, and presenting a broad array of unpublished examples and case studies. The book is mainly aimed to professional palaeobiologists working with Cenozoic land mammals, but the scope of the book is broad enough to fit the interest for evolutionary biologists, paleoclimatologists and paleoecologists. The volume is divided in four parts. The first part includes two chapters on the development of large paleobiological databases, providing a first-hand account on the logic and the functioning of these databases. This is a much-needed perspective which is ignored by most researchers and users of such databases and, even if centered in the NOW database, the lessons that can be learned from this part can be extended to other examples. After this introductory part, the body of the book follows and is divided into three parts: patterns in regional faunas; large scale patterns and processes; and ecological, biogeographical and evolutionary patterns of key taxa. Each chapter is written by well-known specialists in the field, with some participation of members of the NOW advisory board. The array of selected mammal taxa ranges from carnivores, equids, ruminants and rodents to the genus Homo. The topics studied also include the diversification and radiation of major clades, large-scale paleobiogeographical patterns, the evolution of ecomorphological patterns and paleobiological problems such as evolution of body size or species longevity. In most cases the results are discussed in relation to protracted environmental or paleogeographic changes.

Over the past twenty years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before. The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the "monkey business of creationism," Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of "missing links" that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process. Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as a leading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.
