How Fast Did T Rex Run

The revolution in science that is transforming our understanding of dinosaurs In just the past twenty years, we have learned more about dinosaurs than we did in the previous two centuries. This book describes the extraordinary advances in palaeontology that are beginning to solve many of the mysteries surrounding these marvelous prehistoric creatures, from their ways of communicating to their mating habits, the color of their skin, their migration patterns and extinction. How did dinosaurs rear their young? What did they eat? What did T. rex actually do with those tiny arms? David Hone draws on his own discoveries at the forefront of dinosaur science to illuminate these and other questions. Each chapter in this lively and informative book covers a key topic in dinosaur science, such as origins, diversity, evolution, habitats, anatomy, behaviour, ecology and dinosaur descendants—the birds. For each topic, Hone discusses the history of what palaeontologists thought in the past, the new insights we are gleaning from recent fossil finds and the latest technologies and the gaps in our knowledge that still remain. He shares his own predictions about the research areas that may produce the next big ideas in dinosaur science and addresses the unknowns we may never solve. How Fast Did T. rex Run? reveals everything we now know about dinosaurs—and everything we don’t—and charts thrilling new directions for tomorrow’s generation of dinosaur scientists.

Middle school readers can journey into the prehistoric world of tyrannosaurs and discover what it was like to excavate the world's largest T. rex skeleton.

Accompanying CD-ROM has supplementary materials related to chapters 7 (color images of the black and white figures in the book), 11 (Flash-animated movie about tyrannosaurid postures), and 13 (skull bone atlas).

It was smelly, dirty and the SCARIEST creature that EVER lived. BUT T. REX... wasn't the BIGGEST dinosaur ever it wasn't a stupid dinosaur and it wasn't even hungry all the time. NOW YOU KNOW a bit about T.REX, find out ALL the facts inside

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.

'Gripping and wonderfully informative' Tom Holland, New Statesman Adored by children and adults alike, Tyrannosaurus is the most famous dinosaur in the world, one that pops up again and again in pop culture, often battling other beasts such as King Kong, Triceratops or velociraptors in Jurassic Park. But despite the hype, Tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right, and are among the best-studied of all dinosaurs. Tyrannosaurs started small, but over the course of 100 million years evolved into the giant carnivorous bone-crushers that continue to inspire awe in palaeontologists, screenplay writers, sci-fi novelists and the general public alike. Tyrannosaurus itself was truly impressive; it topped six tons, was more than 12m (40 feet) long, and had the largest head and most powerful bite of any land animal in history. The Tyrannosaur Chronicles tracks the rise of these dinosaurs, and presents the latest research into their biology, showing off more than just their impressive statistics – tyrannosaurs had feathers and fought and even ate each other. This book presents the science behind this research; it tells the story of the group through their anatomy, ecology and behaviour, exploring how they came to be the dominant terrestrial predators of the Mesozoic and, in more recent times, one of the great icons of biology.

The Tyrannosaurus rex has long been hailed as the king of the dinosaurs, but what do scientists really know about this prehistoric creature? Inside Out: T. Rex shows you all the clues we've gathered! Inside Out: T. Rex offers clues to understanding the most compelling and mysterious dinosaur of them all. Loaded with awesome illustrations and captivating text, a die-cut model within the book’s pages will take you inside T. rex’s body to reveal, layer by layer, how these giant beasts lived more than 65 million years ago. You won't need a time machine to see this giant, fearsome predator in amazing detail! Each page of Inside Out: T. Rex will bring you even deeper into the world of the Tyrannosaurus rex. You will be amazed by how its specialized anatomy, from its razor-sharp teeth ,to its massive size, to its squishy insides established it as the top of the prehistoric food chain.

For many people, the first thing that comes to mind when they think of dinosaurs is the fearsome T. Rex. As a fierce hunter with a voracious appetite, this giant prowled through the swampy forests of the late Cretaceous period on its two powerful hind legs. In this penetrating volume, young scientists will find out about this dinosaur’s senses, why its front arms were so tiny, and all about its razor-sharp teeth.
