Darin A. Croft is Associate Professor of Anatomy at Case Western Reserve University and a research associate at several museums, including the Cleveland Museum of Natural History. He is an authority on the extinct mammals of South America and has active field programs in the Andes of Chile and Bolivia.Velizar Simeonovski is an artist based in Chicago who specializes in life reconstructions of extinct species and visualizations of ancient landscapes. His works have been featured in scientific journals and magazines, in the book Extinct Madagascar: Picturing the Island's Past, and in museum exhibits in the US and in his home country of Bulgaria.

"Organized as a 'walk through time' and featuring species from 15 important fossil sites, this book is the most extensive and richly illustrated volume devoted exclusively to the Cenozoic mammals of South America."—BirdBooker Report"This handsome book, written by a leading expert in South American paleontology, is profusely illustrated with maps, time charts, color photographs of fossils, and exquisite life reconstructions. The book is accessible to the general reader, and it will appeal to any individual, young and old alike, interested in the fossil record, as well as to students and scholars of paleontology who work in other parts of the globe."—Choice"An expert in fossil mammals from South America, this is Croft's magnum opus on his life's passion."—Twilight Beasts"Given the wealth of unfamiliar animals the volume presents, even readers well versed in vertebrate biodiversity willnd it rewarding."—The Quarterly Review of Biology"It is by far the best and most satisfying book-sized work that looks at South America's extinct fauna so far, and it is unique in its depth of coverage and quality of content. I encourage you to get hold of a copy yourself."—Scientific American Blog Network"All these considerations make this book a great source of information for the non-specialist, and a nice summary for those researchers looking for a synthesis of Cenozoic South American fossil sites."—J Mammal Evol"Horned Armadillos and Rafting Monkeys is an excellent work that will be of interest to anyone that appreciates the extraordinary world of extinct and living mammals, extinction processes, and the loss of biodiversity, and the unique natural history of South America. The combination of scientific information and vivid paleoart reconstructions makes this book a valuable source for an appreciation of these ancient beasts and the ecosystems in which they lived."—Oxford University Press Journals"Well-written and easy for the nonspecialist to understand, this is also a most needed updating of this subject, much in the line of classic works such as Simpson's The Beginning of the Age of Mammals in South America and Patterson and Pascual's The Fossil Mammal Fauna of South America."—Richard Fariña, coauthor Megafauna: Giant Beasts of Pleistocene South America"Horned Armadillos and Rafting Monkeys is a magnificent book, with splendid and exacting illustrations, a necessary update between two covers for specialists as well as for palaeontologists unfamiliar with South America. It is also an accessible book for the educated public. Darin Croft's writing project is unquestionably useful. Velizar Simeonovski has proposed a daunting challenge to the next generation of illustrators."—Ephraim Nissan, Priscum, The Newsletter of the Palentological Society
