Download or read book Evolution of Tertiary Mammals of North America Volume 2 Small Mammals Xenarthrans and Marine Mammals written by Christine M. Janis and published by Cambridge University Press. This book was released on 2008-06-12 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume completes the unique survey of North American Tertiary mammals, and covers all the remaining taxa not contained in Volume 1. It provides a complete listing of mammalian diversity over time and space, and evaluates the effect of biogeography and climatic change on evolutionary patterns and faunal transitions, with the distribution in time and space of each taxon laid out in a standardized format. It contains six summary chapters that integrate systematic and biogeographic information for higher taxa, and provides a detailed account of the patterns of occurrence for different species at hundreds of different fossil localities, with the inclusion of many more localities than were contained in the first volume. With over thirty chapters, each written by leading authorities, and an addendum that updates the occurrence and systematics of all of the groups covered in Volume 1, this will be a valuable reference for paleontologists and zoologists.

Download or read book The White River Badlands written by Rachel C. Benton and published by Indiana University Press. This book was released on 2015-05-25 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide to the South Dakota region that houses the world’s richest fossil beds does “an excellent job of presenting the current state of knowledge” (Choice). The forbidding Big Badlands in Western South Dakota contain the richest fossil beds in the world. Even today these rocks continue to yield new specimens brought to light by snowmelt and rain washing away soft rock deposited on a floodplain long ago. The quality and quantity of the fossils are superb: most of the species to be found there are known from hundreds of specimens. The fossils in the White River Group (and similar deposits in the American west) preserve the entire late Eocene through the middle Oligocene, roughly 35-30 million years ago and more than thirty million years after non-avian dinosaurs became extinct. The fossils provide a detailed record of a period of abrupt global cooling and what happened to creatures who lived through it. This book is a comprehensive reference to the sediments and fossils of the Big Badlands, and also touches on National Park Service management policies that help protect such significant fossils. Includes photos and illustrations “A worthy successor to the work of O’Harra.” —Journal of Vertebrate Paleontology

Download or read book Species Species Concepts and Primate Evolution written by William H. Kimbel and published by Springer Science & Business Media. This book was released on 2013-12-18 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: A world of categones devmd of spirit waits for life to return. Saul Bellow, Humboldt's Gift The stock-in-trade of communicating hypotheses about the historical path of evolution is a graphical representation called a phylogenetic tree. In most such graphics, pairs of branches diverge from other branches, successively marching across abstract time toward the present. To each branch is tied a tag with a name, a binominal symbol that functions as does the name given to an individual human being. On phylogenetic trees the names symbolize species. What exactly do these names signify? What kind of information is communicated when we claim to have knowledge of the following types? "Tetonius mathewzi was ancestral to Pseudotetonius ambiguus. " "The sample of fossils attributed to Homo habzlis is too variable to contain only one species. " "Interbreeding populations of savanna baboons all belong to Papio anubis. " "Hylobates lar and H. pileatus interbreed in zones of geographic overlap. " While there is nearly universal agreement that the notion of the speczes is fundamental to our understanding of how evolution works, there is a very wide range of opinion on the conceptual content and meaning of such particular statements regarding species. This is because, oddly enough, evolutionary biolo gists are quite far from agreement on what a species is, how it attains this status, and what role it plays in evolution over the long term.

Download or read book The Bone Field written by Leonard Krishtalka and published by . This book was released on 2019-06-20 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Hard-Boiled Detective Series Uncovers Bones, Murder & History. Paleontologist turned private investigator, Harry Przewalski, excavates the dirty underbelly of people's lives, unearthing sexual betrayals, treachery, fraud and murder buried beneath the science of petrified shards, skin and bones. Ultimately, he must face a brutal killing in his own past, when he fled to a desert war and came back with a gun and a license to detect. In his first case, The Bone Field, Przewalski chases a missing paleontologist across 80 million years of intrigue and death, from a Wyoming bone field of petrified skeletons to the bone rooms of the museum. World-renowned museum paleontologist, Peter Marchand, goes missing while leading a dinosaur dig in the sweltering, desert badlands of Wyoming. He has made enemies from his serial womanizing, ruthless dealings, religious blasphemy, and unorthodox theories. Hired to find him, Pittsburgh private detective Harry Przewalski uncovers a tangle of sexual deceit, betrayal, and scientific fraud. Ultimately, he must excavate the nightmares in his own extinct past to keep from being killed. The first installment in the Harry Przewalski series. The second book in the series is Death Spoke.
