Book Description
Excerpt from History of Land Mammals in the Western Hemisphere One afternoon in June, 1876, three Princeton undergraduates were lying under the trees on the canal bank, making a languid pretence of preparing for an examination. Suddenly, one of the trio remarked: "I have been reading an old magazine article which describes a fossil-collecting expedition in the West; why can't we get up something of the kind?" The others replied, as with one voice, "We can; let's do it." This seemingly idle talk was, for Osborn and myself, a momentous one, for it completely changed the careers which, as we then believed, had been mapped out for us. The random suggestion led directly to the first of the Princeton palaeontological expeditions, that of 1877, which took us to the "Bad Lands" of the Bridger region in southwestern Wyoming. The fascination of discovering and exhuming with our own hands the remains of the curious creatures which once inhabited North America, but became extinct ages ago, has proved an enduring delight. It was the wish to extend something of this fascinating interest to a wider circle, that occasioned the preparation of this book. The western portion of North America has preserved a marvellous series of records of the successive assemblages of animals which once dwelt in this continent, and in southernmost South America an almost equally complete record was made of the strange animals of that region. For the last half-century, or more, many workers have cooperated to bring this long-vanished world to light and to decipher and interpret the wonderful story of mammalian development in the western hemishere.

Book Description
In the tradition of G. G. Simpson's classic work, Kenneth D. Rose's The Beginning of the Age of Mammals analyzes the events that occurred directly before and after the mysterious K-T boundary which so quickly thrust mammals from obscurity to planetary dominance. Rose surveys the evolution of mammals, beginning with their origin from cynodont therapsids in the Mesozoic, contemporary with dinosaurs, through the early Cenozoic, with emphasis on the Paleocene and Eocene adaptive radiations of therian mammals. Focusing on the fossil record, he presents the anatomical evidence used to interpret behavior and phylogenetic relationships. The life's work of one of the most knowledgeable researchers in the field, this richly illustrated, magisterial book combines sound scientific principles and meticulous research and belongs on the shelf of every paleontologist and mammalogist.

Book Description
Although its history is etched on canyon walls reaching back twenty million years, the Niobrara is very much a river of today. Stretching 535 miles from its headwaters to the Missouri River, it is one of Nebraska?s least altered waterways and is designated as a national scenic river. Its waterfalls and wildlife make it a haven for outdoor enthusiasts, but pressures from development still threaten its scenic and ecological wonders. ø This first book-length study of the Niobrara is a comprehensive look at an ecological treasure. Paul A. Johnsgard reviews the river?s history from its geologic past through prehistoric settlement to the present and highlights its historical and biological features. ø Writing from this crossroads of eastern and western species, Johnsgard also describes the Niobrara?s varied plants and animals, providing extensive information on bird populations. He offers portraits of sixteen species of special conservation concern, such as the black-tailed prairie dog and the olive-backed pocket mouse. Drawings by Johnsgard, information tables on various species, plus site lists make the book an invaluable reference. It conveys the Niobrara?s value as a recreational and scientific resource to help visitors better appreciate this riparian paradise while offering specialists an unimpeachable guide to its scientific riches. The Niobrara includes chapters by Jon Farrar and Duane Gudgel.
