“A valuable volume detailing an underexplored region of the world of dinosaurs . . . essential reading for any dino-devotee.” —ForeWord Dinosaurs of Darkness opens a doorway to a fascinating former world, between 100 million and 120 million years ago, when Australia was far south of its present location and joined to Antarctica. Dinosaurs lived in this polar region. How were the polar dinosaurs discovered? What do we now know about them? Thomas H. Rich and Patricia Vickers-Rich, who have played crucial roles in their discovery, describe how they and others collected the fossils indispensable to our knowledge of this realm and how painstaking laboratory work and analyses continue to unlock the secrets of the polar dinosaurs. This scientific adventure makes for a fascinating story: it begins with one destination in mind and ends at another, arrived at by a most roundabout route, down byways and back from dead ends. Dinosaurs of Darkness is a personal, absorbing account of the way scientific research is actually conducted and how hard—and rewarding—it is to mine the knowledge of this remarkable life of the past. The award-winning first edition has now been thoroughly updated with the latest discoveries and interpretations, along with over 100 new photographs and charts, many in color.

Eight-year-old Jack and his younger sister Annie find a magic treehouse, which whisks them back to an ancient time zone where they see live dinosaurs.

Bobby wakes up in the middle of the night to see an enormous dinosaur sneaking past his window. He goes out into the night and finds lots of dinosaurs playing in the city square. At first they threaten Bobby, then they all end up playing hide and seek.

“Takes readers on illuminating scientific adventure, beginning sixty-six million years ago, that connects dinosaurs, comets, DNA, and the future of the planet.” —Huffington Post In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times–bestselling author of Warped Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth. Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs. Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things. “Randall has woven a beautiful account of how life on Earth is intimately connected to the cosmos.” —The Daily Telegraph (UK)
