Horns, Tusks, and Flippers: The Evolution of Hoofed Mammals

by Donald R. Prothero

Since the extinction of the dinosaurs, hoofed mammals have been the planet's dominant herbivores. Native to all continents except Australia and Antarctica, they include not only even-toed artiodactyls (pigs, hippos, camels, deer, antelopes, giraffes, sheep, goats, and cattle) and odd-toed perissodactyls (horses and rhinos), but also tethytheres (elephants and their aquatic relatives, manatees and seas cows) and cetaceans (whales and dolphins), which descended from hoofed land mammals. Recent paleontological and biological discoveries have deepened our understanding of their evolution and in some cases have made previous theories obsolete. In Horns, Tusks, and Flippers , Donald R. Prothero and Robert M. Schoch present a compelling new evolutionary history of these remarkable creatures, combining the latest scientific evidence with the most current information about their ecology and behavior. Using an approach based on cladistics, the authors consider both living and extinct ungulates. Included in their discussion are the stories of rhinos, whose ancestors include both dinosaur-sized hornless species and hippo-like river waders; elephants, whose earliest ancestors had neither tusks nor trunks; and whales, whose descent from hoofed mesonychids has never properly been described for the lay audience. Prothero and Schoch also update the evolutionary history of the horse, correcting the frequent errors made in textbooks and popular works, and they make available to the general public new evidence about the evolution of camels, horned antelopes, and cattle. In addition, they raise important conservation issues and relate anecdotes of significant fossil finds. Scientifically accurate and up to date, generously illustrated, and clearly written, Horns, Tusks, and Flippers is a useful and much-needed resource for specialists in the fields of paleontology, zoology, ecology, and evolutionary biology, as well as for general readers interested in learning more about the story of life on earth.

About the author

Donald R. Prothero is a Professor of Geology at Occidental College and Lecturer in Geobiology at the California Institute of Technology. He teaches Physical and Historical Geology, Sedimentary Geology, and Paleontology. His specialties are mammalian paleontology and magnetic stratigraphy of the Cenozoic. His current research focuses on the dating of the climatic changes that occurred between 30 and 40 million years ago, using the technique of magnetic stratigraphy. Dr. Prothero has been a Guggenheim and NSF Fellow, a Fellow of the Linnean Society, and in 1991 received the Schuchert Award of the Paleontological Society for outstanding paleontologist under the age of 40, the same award won by the renowned paleontologist Stephen Jay Gould. He has authored or co-edited numerous books, including Horns, Tusks, Hooves and Flippers: The Evolution of Hoofed Mammals, the best-selling textbook from McGraw-Hill, Evolution of the Earth, Evolution: What the Fossils Say & Why it Matters, Bringing Fossils to Life, After the Dinosaurs, and the textbook Sedimentary Geology. He is also a Technical Editor of the Journal of Paleontology.

Reviews

[Sue · Rating 5 out of 5]

I have read this book cover-to-cover & I can't recommend or praise it highly enough. It is clearly written & very informative - where else do you get an in-depth description & discussion of the various species of rhinoceros species, both extant and extinct... except in Prothero's other books, such as 'Rhinoceros Giants'.

An excellent read & definitely one for the reference bookshelf.
