In this fascinating and accessible overview, renowned paleontologist Michael J. Benton reveals how our understanding of dinosaurs is being transformed by recent fossil finds and new technology.Over the past twenty years, the study of dinosaurs has transformed into a true scientific discipline. New technologies have revealed secrets locked in prehistoric bones that no one could have previously predicted. We can now work out the color of dinosaurs, the force of their bite, their top speeds, and even how they cared for their young.Remarkable new fossil discoveries—giant sauropod dinosaur skeletons in Patagonia, dinosaurs with feathers in China, and a tiny dinosaur tail in Burmese amber—remain the lifeblood of modern paleobiology. Thanks to advances in technologies and methods, however, there has been a recent revolution in the scope of new information gleaned from such fossil finds.In Dinosaurs Rediscovered, leading...

In a sunlit clearing in central Gondwana, on an otherwise ordinary day in the late Cretaceous, the seeds of Earth's first and greatest civilization were sown in the grisly aftermath of a Tyrannosaurus' lunch. Throughout the universe, intelligence is a rare and fragile commodity – a fleeting glimmer in the long night of cosmic history. That Earth should harbour not just one but two intelligent species at the same time, defies the odds. That these species, so unalike – and yet so complementary – should forge an alliance that kindled a civilization defies logic. But time is endless and everything comes to pass eventually... The alliance between ants and dinosaurs, was of course, based on dentistry. Yet from such humble beginnings came writing, mathematics, computers, fusion, antimatter and even space travel – a veritable Age of Wonder! But such magnificent industry comes at a price – a price paid first by Earth's...

At the end of the time of the dinosaurs, Transylvania was an island in what was to become southeastern Europe. The island's limited resources affected the size and life histories of its animals, resulting in a local dwarfism. For example, sauropods found on the island measured only six meters long, while their cousins elsewhere grew up to five times larger. Here, David B. Weishampel and Coralia-Maria Jianu present unique evolutionary interpretations of this phenomenon.The authors bring together the latest information on the fauna, flora, geology, and paleogeography of the region, casting these ancient reptiles in their phylogenetic, paleoecological, and evolutionary contexts. What the authors find is that Transylvanian dinosaurs experienced a range of unpredictable successes as they evolved.Woven throughout the detailed history and science of these diminutive dinosaurs is the fascinating story of the man who first discovered them, the mysterious twentieth-century...

"Dinosaurs in the Attic" is a chronicle of the expeditions, discoveries, and scientists behind the greatest natural history collection every assembled. Written by former "Natural History" columnist Douglas Preston, who worked at the American Museum of Natural History for seven years, this is a celebration of the best-known and best-loved museum in the United States.

All five of David Drake's time travel stories collected for the first time in one volume, including dinosaur tale "Time Safari." Henry Vickers's job is to keep clients safe from the dinosaurs they're hunting. That's the easy part. The hard part is to keep the clients safe from themselves and each other. Men with enough money to go into the past to hunt the largest land animals of all time are powerful and self-willed. Some make an effort to act like decent human beings, but more are selfish, stupid, sadistic--or all three together. The few women are likely to be worse. Vickers doesn't expect rich people to understand the dangers of where they are and what they're doing; he doesn't expect them to be competent with the powerful rifles they carry; and he particularly doesn't expect them to be reasonable. He treats his clients' behavior as he does the rain and the baking heat--the cost of having a life he loves and which he couldn't afford in any other way. But no matter how detached Vickers tries to be, eventually there are moral questions that he can't ignore. And when Henry Vickers starts to behave like a human being instead of a hunting guide, things get really dangerous. And in a complete change of pace: "Travellers." An airship is crossing the United States in 1897 in search of the weird and the wonderful. The two teenagers aboard know that the airship's captain is a great scientist and inventor--but they don't know how much more he is also. All five of David Drake's time travel stories collected for the first time.**

What if we woke up one morning all of the dinosaur bones in the world were gone? How would we know these iconic animals had a 165-million year history on earth, and had adapted to all land-based environments from pole to pole? What clues would be left to discern not only their presence, but also to learn about their sex lives, raising of young, social lives, combat, and who ate who? What would it take for us to know how fast dinosaurs moved, whether they lived underground, climbed trees, or went for a swim?Welcome to the world of ichnology, the study of traces and trace fossils—such as tracks, trails, burrows, nests, toothmarks, and other vestiges of behavior—and how through these remarkable clues, we can explore and intuit the rich and complicated lives of dinosaurs. With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life...
