This book was released on 1995-08-31 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bug Creek assemblages from Montana, transitional in composition between typical Cretaceous and Paleocene vertebrate faunas, are critical to K-T extinction debates because they have been used to support both gradual and catastrophic K-T extinction scenarios. Geological and palynological data from McGuire Creek indicate that Bug Creek assemblages are Paleocene and restricted to channel fills entrenched into older sediments, suggesting that the Cretaceous component of the assemblage was reworked. Thus, the author concludes, "Paleocene dinosaurs" are an illusion and the K-T survival rate of mammals is low because the presence of Cretaceous mammals in Bug Creek assemblages is also the result of reworking.

Download or read book The Complete Dinosaur written by M. K. Brett-Surman and published by Indiana University Press. This book was released on 2012-06-27 with total page 1160 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new edition of the illustrated compendium that is “a gift to serious dinosaur enthusiasts” (Science). What do we know about dinosaurs, and how do we know it? How did they grow, move, eat, and reproduce? Were they warm-blooded or cold-blooded? How intelligent were they? How are the various groups of dinosaurs related to each other, and to other kinds of living and extinct vertebrates? What can the study of dinosaurs tell us about the process of evolution? And why did typical dinosaurs become extinct? These questions and more are addressed in this new, expanded edition of The Complete Dinosaur. Written by leading experts on the “fearfully great” reptiles, the book covers what we have learned about dinosaurs, from the earliest discoveries to the most recent controversies. Where scientific contention exists, the editors have let the experts agree to disagree. The Complete Dinosaur is a feast for serious dinosaur lovers, from the enthusiastic amateur to the professional paleontologist. Praise for the first edition: “An excellent encyclopedia that serves as a nice bridge between popular and scholarly dinosaur literature.” —Library Journal (starred review) “Stimulating armchair company for cold winter evenings. . . . Best of all, the book treats dinosaurs as intellectual fun.” —New Scientist “Useful both as a reference and as a browse-and-enjoy compendium.” —Natural History “Copiously illustrated and scrupulously up-to-date.” —Publishers Weekly “The amount of information in [these] pages is amazing. This book should be on the shelves of dinosaur freaks as well as those who need to know more about the paleobiology of extinct animals. It will be an invaluable library reference.” —American Reference Books Annual

Download or read book Otherlands written by Thomas Halliday and published by Random House. This book was released on 2022-02-01 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Immersive . . . bracingly ambitious . . . rewinds the story of life on Earth—from the mammoth steppe of the last Ice Age to the dawn of multicellular creatures over 500 million years ago.”—The Economist LONGLISTED FOR THE BAILLIE GIFFORD PRIZE • “One of those rare books that’s both deeply informative and daringly imaginative.”—Elizabeth Kolbert, author of Under a White Sky ONE OF THE BEST BOOKS OF THE YEAR: The New Yorker, Prospect (UK) The past is past, but it does leave clues, and Thomas Halliday has used cutting-edge science to decipher them more completely than ever before. In Otherlands, Halliday makes sixteen fossil sites burst to life on the page. This book is an exploration of the Earth as it used to exist, the changes that have occurred during its history, and the ways that life has found to adapt―or not. It takes us from the savannahs of Pliocene Kenya to watch a python chase a group of australopithecines into an acacia tree; to a cliff overlooking the salt pans of the empty basin of what will be the Mediterranean Sea just as water from the Miocene Atlantic Ocean spills in; into the tropical forests of Eocene Antarctica; and under the shallow pools of Ediacaran Australia, where we glimpse the first microbial life. Otherlands also offers us a vast perspective on the current state of the planet. The thought that something as vast as the Great Barrier Reef, for example, with all its vibrant diversity, might one day soon be gone sounds improbable. But the fossil record shows us that this sort of wholesale change is not only possible but has repeatedly happened throughout Earth history. Even as he operates on this broad canvas, Halliday brings us up close to the intricate relationships that defined these lost worlds. In novelistic prose that belies the breadth of his research, he illustrates how ecosystems are formed; how species die out and are replaced; and how species migrate, adapt, and collaborate. It is a breathtaking achievement: a surprisingly emotional narrative about the persistence of life, the fragility of seemingly permanent ecosystems, and the scope of deep time, all of which have something to tell us about our current crisis.
Download or read book A Miocene 10 12 Ma Evergreen Laurel Oak Forest from Carmel Valley California written by Daniel I. Axelrod and published by Univ of California Press. This book was released on 2000-06-12 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a study of the Miocene Carmel flora of California, an evergreen laurel–oak forest that grew in a mild temperate (mean annual temperature of 15 degrees C), frost-free climate, with annual precipitation of about 760 mm (30 in.). Collectively, the Carmel and other Miocene floras like the San Pablo and Temblor (broad-leafed deciduous trees, with few evergreen species), the Puente (evergreen oak forest with chaparral species), the Mint Canyon, Ricardo, and Tehachapi (numerous arid subtropical scrub associated with oak woodland and chaparral species) suggest they foreshadowed a similar distribution of the different California vegetation zones today.
Download or read book Biostratigraphy and Vertebrate Paleontology of the San Timoteo Badlands Southern California written by L. Barry Albright III and published by Univ of California Press. This book was released on 2000-03-08 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author describes forty-two fossil taxa recovered during a study of the San Timoteo Badlands that used magnetobiostratigraphy to develop a temporal framework for addressing the tectonic evolution of southern California over the last 6 million years. For the Pliocene, small mammals are an effective means of correlating a magnetostratigraphy to the Geomagnetic Polarity Time Scale when radioisotopic dates are unobtainable.

Download or read book Mammals from the Age of Dinosaurs written by Zofia Kielan-Jaworowska and published by Columbia University Press. This book was released on 2005-02-05 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few aspects of American military history have been as vigorously debated as Harry Truman's decision to use atomic bombs against Japan. In this carefully crafted volume, Michael Kort describes the wartime circumstances and thinking that form the context for the decision to use these weapons, surveys the major debates related to that decision, and provides a comprehensive collection of key primary source documents that illuminate the behavior of the United States and Japan during the closing days of World War II. Kort opens with a summary of the debate over Hiroshima as it has evolved since 1945. He then provides a historical overview of thye events in question, beginning with the decision and program to build the atomic bomb. Detailing the sequence of events leading to Japan's surrender, he revisits the decisive battles of the Pacific War and the motivations of American and Japanese leaders. Finally, Kort examines ten key issues in the discussion of Hiroshima and guides readers to relevant primary source documents, scholarly books, and articles.

Download or read book The Eternal Frontier written by Tim Flannery and published by Open Road + Grove/Atlantic. This book was released on 2015-01-07 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive history of the continent, “full of engaging and attention-catching information about North America’s geology, climate, and paleontology” (The Washington Post Book World). Here, “the rock star of modern science” tells the unforgettable story of the geological and biological evolution of the North American continent, from the time of the asteroid strike that wiped out the dinosaurs 65 million years ago to the present day (Jared Diamond, Pulitzer Prize–winning author of Guns, Germs, and Steel). Flannery describes the development of North America’s deciduous forests and other flora, and tracks the migrations of various animals to and from Europe, Asia, and South America, showing how plant and animal species have either adapted or become extinct. The story spans the massive changes wrought by the ice ages and the coming of the Native Americans. It continues right up to the present, covering the deforestation of the Northeast, the decimation of the buffalo, and other consequences of frontier settlement and the industrial development of the United States. This is science writing at its very best—both an engrossing narrative and a scholarly trove of information that “will forever change your perspective on the North American continent” (The New York Review of Books).
