Book Description
To help us understand what happened during the Ice Age, Peter Ward takes us on a tour of other mass extinctions through earth's history. He presents a compelling account of the great comet crash that killed off the dinosaurs, and describes other extinctions that were even more extensive. In so doing, he introduces us to a profound paradigm shift now taking place in paleontology: rather than arising from the gradual workings of everyday forces, all mass extinctions are due to unique, catastrophic events. Written with an irresistible combination of passion and expertise, The Call of Distant Mammoths is an engaging exploration of the history of life and the importance of humanity as an evolutionary force. "Carefully argued...an intelligent and compelling book."-THE OLYMPIAN, SEATTLE, WASHINGTON "Ward deftly summarizes a large body of scientific literature, simplifying complex ideas for the general reader without condescension."-PUBLISHERS WEEKLY "Did the overkill really happen?...Peter Ward deftly summarizes the arguments...Ward tells (the story) well."-THE NEW SCIENTIST

Book Description
In the days when dinosaurs dominated the earth, their marine counterparts - every bit as big and ferocious - reigned supreme in prehistoric seas. In this book, Richard Ellis takes us back to the Mesozoic era to resurrect the fascinating lives of these giant seagoing reptiles. fierce predators, speculates on their habits, and tells how they eventually became extinct - or did they? He traces the 200-million-year history of the great ichthyosaurs, plesiosaurs and mosasaurs who swam the ancient oceans - and who may, according to some, still frequent the likes of Loch Ness. animal that looked like a crocodile crossed with a shark the size of a small yacht. With its impossibly long neck, Plesiosaurus conybeari has been compared to a giant snake threaded through the body of a turtle. At a length of nearly 60 feet, Mosasaurus hoffmanni boasted powerful jaws that could crunch up even the hardest-shelled giant sea turtle. And Kronosaurus queenslandicus, perhaps the most formidable of the lot, had a skull nine feet long - more than twice that of Tyrannosaurus rex - with teeth to match. reconstruct their lives and habitats. Their fossils have been found all over the world - in Europe, Australia, Japan and even Kansas - in lands that once lay on the floors of Jurassic and Triassic seas. Along the way, the book also provides intriguing insights into and entertaining tales about the work, discoveries and competing theories that compose the world of vertebrate paleontology. The text is also accompanied by Ellis' own illustrations of how these creatures probably appeared and, through these likenesses, we are invited to speculate on their locomotion, their predatory habits and their lifestyles.

Book Description
Limulus in the Limelight: A Species 350 Million Years in the Making and in Peril? contains 14 chapters covering the horseshoe crab's biology, ecology and evolutionary development. The book is a result of three mini-conferences held between 1996 and 2000 celebrating the populations in NY harbor. This book exposes the impacts of over fishing on this species; clarifies the future research agenda for the species worldwide and emphasizes the need for conservation of this fascinating creature's estuaries/ocean habitats. Biologists, ecologists, science educators, and conservationists will welcome this book because it is aimed at the preservation of Limulus, not only for its pharmacological interest but for the mystery related to its longevity. Limulus is a unique animal which has provided numerous uses for man over the years, from fertilizer to bait to medical research. However, if this species is not protected soon, it will be lost for the future.

Book Description
The carefully crafted, meditative essays in On the Shoreline of Knowledge sometimes start from unlikely objects or thoughts, a pencil or some fragments of commonplace conversation, but they soon lead the reader to consider fundamental themes in human experience. The unexpected circumnavigation of the ordinary unerringly gets to the heart of the matter. Bringing a diverse range of material into play, from fifteenth-century Japanese Zen Buddhism to how we look at paintings, and from the nature of a briefcase to the ancient nest-sites of gyrfalcons, Chris Arthur reveals the extraordinary dimensions woven invisibly into the ordinary things around us. Compared to Loren Eiseley, George Eliot, Seamus Heaney, Aldo Leopold, V. S. Naipaul, W. G. Sebald, W. B. Yeats, and other literary luminaries, he is a master essayist whose work has quietly been gathering an impressive cargo of critical acclaim. Arthur speaks with an Irish accent, rooting the book in his own unique vision of the world, but he addresses elemental issues of life and death, love and loss, that circle the world and entwine us all.
