Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.
Elaborate pop-ups include an awesome, futuristic laboratory and an incredible cityscape complete with rampaging dinos, while lift-the-flaps, moving parts, and a few hidden secrets add extra fun The Time Pirates' visit to the museum's "Dinorama" exhibition is interrupted when an army of real-life armored dinosaurs invade. With evil genius Tempus Fugit controlling the prehistoric predators, there's no time to lose if the Time Pirates are going to save the city from total dino destruction! An action-packed story, press-out pieces, two stand-alone pop-up dinosaurs, and an amazing pop-up cityscape and futuristic laboratory make this the perfect book for young adventure fans.

But they'll need each other, the wisdom of their parents, and their faith in God to survive what they find!

What can long-dead dinosaurs teach us about our future? Plenty, according to paleontologist Kenneth Lacovara, who has discovered some of the largest creatures to ever walk the Earth. By tapping into the ubiquitous wonder that dinosaurs inspire, Lacovara weaves together the stories of our geological awakening, of humanity’s epic struggle to understand the nature of deep time, the meaning of fossils, and our own place on the vast and bountiful tree of life. Go on a journey––back to when dinosaurs ruled the Earth––to discover how dinosaurs achieved feats unparalleled by any other group of animals. Learn the secrets of how paleontologists find fossils, and explore quirky, but profound questions, such as: Is a penguin a dinosaur? And, how are the tiny arms of T. rex the key to its power and ferocity? In this revealing book, Lacovara offers the latest ideas about the shocking and calamitous death of the dinosaurs and ties their vulnerabilities to our own. Why Dinosaurs Matter is compelling and engaging—a great reminder that our place on this planet is both precarious and potentially fleeting. “As we move into an uncertain environmental future, it has never been more important to understand the past.”
Dinosaurs, comics, and outer space, together at last! This two-books-in-one format of Blue Apple's acclaimed Balloon Toons series is sure to please kids, parents, and educators alike.
"... are dinosaurs social constructs? Do we really know anything about dinosaurs? Might not all of our beliefs about dinosaurs merely be figments of the paleontological imagination? A few years ago such questions would have seemed preposterous, even nonsensical. Now they must have a serious answer." At stake in the "Science Wars" that have raged in academe and in the media is nothing less than the standing of science in our culture. One side argues that science is a "social construct," that it does not discover facts about the world, but rather constructs artifacts disguised as objective truths. This view threatens the authority of science and rejects science's claims to objectivity, rationality, and disinterested inquiry. Drawing Out Leviathan examines this argument in the light of some major debates about dinosaurs: the case of the wrong-headed dinosaur, the dinosaur "heresies" of the 1970s, and the debate over the extinction of dinosaurs. Keith Parsons claims that these debates, though lively and sometimes rancorous, show that evidence and logic, not arbitrary "rules of the game," remained vitally important, even when the debates were at their nastiest. They show science to be a complex set of activities, pervaded by social influences, and not easily reducible to any stereotype. Parsons acknowledges that there are lessons to be learned by scientists from their would-be adversaries, and the book concludes with some recommendations for ending the Science Wars.
