Xiaoming Wang has spent the past 20 years studying the evolutionary history of the family Canidae, and Richard H. Tedford is well known for having established the modern framework for the evolutionary relationship of canids. Combining their research with Mauricio Antón's impeccable reconstructions of both extinct and extant species, Wang and Tedford present a remarkably detailed and nuanced portrait of the origin and evolution of canids over the past 40 million years. The authors cull their history from the most recent scientific research conducted in the vast collections of the American Museum of Natural History and other leading institutions. Perhaps because canids inhabited wide-open terrains, where terrestrial sediments are best preserved, their fossil records, particularly those from North America, are the strongest of their kind among known groups of carnivorans. Such a wonderfully detailed evolutionary history therefore provides access to a natural history that is not possible with many other groups of carnivorans.With their rich fossil records, diverse adaptations to various environments, and different predatory specializations, canids are an ideal model organism for the mapping of predator behaviors and morphological specializations. They also offer an excellent contrast to felids, which remain entrenched in extreme predatory specializations. The innovative illustrated approach in this book is the perfect accompaniment to an extremely important branch of animal and fossil study. It transforms the science of paleontology into a thrilling visual experience and provides an unprecedented reference for anyone fascinated by dogs.
