It produced a cloud of roiling debris that blackened the sky for months as well as other geologic disasters--and triggered the demise of Tyrannosaurus rex. We know what happened largely because Walter Alvarez--synthesizing the findings of experts from a variety of scientific fields--has written a gripping story of the decades-long search for the cause of the dinosaurs' extinction. Painstakingly assembling clues from the Italian Apennines and the depths of the Pacific and presenting them with the excitement of a great novel, T. rex and the Crater of Doom is a book of undeniable importance and irresistible appeal by a major figure in contemporary science. " Engaging and witty. Read Alvarez for and excellent account of how scientists pose questions and seek to solve them." --Scientific American " First-rate...Alvarez provides the up-close tale of the comet or asteroid that wiped out the dinosaurs." --San Francisco Chronicle

    Now computers and genetic engineering have brought one of these magnificent creatures back to life and into the life of a boy named Thor. This moving and suspenseful tale will enchant readers, and offer an irresistible reminder of the bond between the creatures of the wild and the child that lives within us all.

    And despite centuries of study there is always more to know. In 2008, paleontologist John A. Long and a team of researchers revealed their discovery of a placoderm fish fossil, known as “the mother fish,” which at 380 million years old revealed the oldest vertebrate embryo—the earliest known example of internal fertilization. As Long explains, this find led to the reexamination of countless fish fossils and the discovery of previously undetected embryos. As a result, placoderms are now considered to be the first species to have had intimate sexual reproduction or sex as we know it—sort of. Inspired by this incredible find, Long began a quest to uncover the paleontological and evolutionary history of copulation and insemination. In The Dawn of the Deed, he takes readers on an entertaining and lively tour through the sex lives of ancient fish and exposes the unusual mating habits of arthropods, tortoises, and even a well-endowed (16.5 inches!) Argentine Duck. Long discusses these significant discoveries alongside what we know about reproductive biology and evolutionary theory, using the fossil record to provide a provocative account of prehistoric sex. The Dawn of the Deed also explores fascinating revelations about animal reproduction, from homosexual penguins to monogamous seahorses to the difficulties of dinosaur romance and how sexual organs in ancient shark-like fishes actually relate to our own sexual anatomy. The Dawn of the Deed is Long’s own story of what it’s like to be a part of a discovery that rewrites evolutionary history as well as an absolutely rollicking guide to sex throughout the ages in the animal kingdom. It’s natural history with a naughty wink.

    Completely focused on her research, she fears and actively avoids all social contact. Her difficult past has led to an extreme distrust of other people and the ingrained fear that her physical scarring would make it impossible to develop a relationship.Kathleen's quantum physics research guides her development of mathematical formulas and leads to the conclusion that time-travel is possible. Her discovery inexorably sets off a horrifying series of events that results in her temporal displacement into the Pleistocene. She translates into the time of the Younger Dryas - a period where the global temperature abruptly cools an average of ten degrees and causes the advance of glacial ice sheets.She must now learn to survive in a hostile and cold wilderness. The ice-age environment forces her to confront her worst fear as she finds that trust in a handsome, primitive hunter becomes paramount in order to survive.Can she overcome her fear? Will the harsh climate and fierce beasts of the Younger Dryas force her to ignite a carefully suppressed, internal fire, or will she be able to return to the safety of the present?

    Lavishly illustrated with over sixty original artworks, All Yesterdays aims to challenge our notions of how prehistoric animals looked and behaved. As a critical exploration of palaeontological art, All Yesterdays asks questions about what is probable, what is possible, and what is commonly ignored.Written by palaeozoologist Darren Naish, and palaeontological artists John Conway and C.M. Kosemen, All Yesterdays is scientifically rigorous and artistically imaginative in its approach to fossils of the past - and those of the future.

    Diligently researching how to restore his quality of life, she discovered Vet-Stem, a service that provides cutting-edge regeneration therapy for pets, using stem cells harvested from animals' own tissue. Just hours after receiving IV and intra-joint injections, Sam began aging backward--which left Julia wondering why this simple, effective treatment was not available for humans.            Julia suffered from chronic inflammatory bowel disease, and after witnessing Sam's astonishing recovery, she set out on a curious quest: to be treated like a dog by a doctor as competent as her vet! After a four-year wait, Julia became the first American to be successfully cured of a perirectal fistula with stem cells derived from her own fat. With this amazing true story of how a pack of shelter dogs she rescued from death row came to save her life, Julia hopes to inspire and inform readers about exciting healthcare options available to them and their cherished animal companions.

    But what if these beings were more than merely fictions? What if monstrous creatures once roamed the earth in the very places where their legends first arose? This is the arresting and original thesis that Adrienne Mayor explores in The First Fossil Hunters. Through careful research and meticulous documentation, she convincingly shows that many of the giants and monsters of myth did have a basis in fact--in the enormous bones of long-extinct species that were once abundant in the lands of the Greeks and Romans.As Mayor shows, the Greeks and Romans were well aware that a different breed of creatures once inhabited their lands. They frequently encountered the fossilized bones of these primeval beings, and they developed sophisticated concepts to explain the fossil evidence, concepts that were expressed in mythological stories. The legend of the gold-guarding griffin, for example, sprang from tales first told by Scythian gold-miners, who, passing through the Gobi Desert at the foot of the Altai Mountains, encountered the skeletons of Protoceratops and other dinosaurs that littered the ground.Like their modern counterparts, the ancient fossil hunters collected and measured impressive petrified remains and displayed them in temples and museums; they attempted to reconstruct the appearance of these prehistoric creatures and to explain their extinction. Long thought to be fantasy, the remarkably detailed and perceptive Greek and Roman accounts of giant bone finds were actually based on solid paleontological facts. By reading these neglected narratives for the first time in the light of modern scientific discoveries, Adrienne Mayor illuminates a lost world of ancient paleontology. As Peter Dodson writes in his Foreword, "Paleontologists, classicists, and historians as well as natural history buffs will read this book with the greatest of delight--surprises abound."

    Situating these fascinating animals in a broad ecological and evolutionary context, leading dinosaur expert Scott D. Sampson fills us in on the exhilarating discoveries of the past twenty-five years, the most active period in the history of dinosaur paleontology, during which more “new” species were named than in all prior history. With these discoveries—and the most recent controversies—in mind, Sampson reconstructs the odyssey of the dinosaurs from their humble origins on the supercontinent Pangaea, to their reign as the largest animals the planet has ever known, and finally to their abrupt demise. Much more than the story of who ate whom way back when, Dinosaur Odyssey places dinosaurs in an expansive web of relationships with other organisms and demonstrates how they provide a powerful lens through which to observe the entire natural world. Addressing topics such as extinction, global warming, and energy flow, Dinosaur Odyssey finds that the dinosaurs' story is, in fact, a major chapter in our own story.
