An identification guide to the most important and best known dinosaursDo you know the difference between a Coelophysis and a Diplodocus? How much larger than a human was a Spinosarus? Is it likely that the Parasaurolophus made a sound like a trombone? All these questions and many more are answered in Collins Gem Dinosaurs, a highly illustrated guide to the world's very wild life hundreds of millions of years ago.A fully illustrated guide to the lost world of dinosaurs, the book provides descriptions of the most significant features and habits of these fascinating prehistoric reptiles, with profiles of nearly 70 dinosaurs which include in-depth looks at how dinosaurs lived, from keeping warm to moving about.For each species information is given ono What they ate o How their size compares to ours o How they behaved o Where they livedThe book also includes explanations of what the dinosaur names mean and how to pronounce them.

Living Dinosaurs offers a snapshot of our current understanding of the origin and evolution of birds. After slumbering for more than a century, avian palaeontology has been awakened by startling new discoveries on almost every continent. Controversies about whether dinosaurs had real feathers or whether birds were related to dinosaurs have been swept away and replaced by new and more difficult questions: How old is the avian lineage? How did birds learn to fly? Which birds survived the great extinction that ended the Mesozoic Era and how did the avian genome evolve? Answers to these questions may help us understand how the different kinds of living birds are related to one another and how they evolved into their current niches. More importantly, they may help us understand what we need to do to help them survive the dramatic impacts of human activity on the planet.

With his groundbreaking findings and extensive research, palaeontologist and dino hunter Dr Phil Currie challenges the very foundations of traditional dinosaur theories.Seventy million years ago the Mongolian desert was home to the world's biggest, most dangerous carnivores – 5 meters tall, 12 meters long and weighing over 4 tonnes, the Tyrannosaurs were the most formidable hunters to walk the earth. Now, new research emerges that threatens to challenge the foundation of many traditional theories on the biology of these fascinating creatures.Palaeontologist and dino hunter Dr Phil Currie is out to prove how dinosaurs actually lived. He and his team have been searching for the fossilised truth about dinosaurs in the most extreme conditions; searing 40 degree heat, intense sandstorms and the constant threat of illegal poachers.Currie's groundbreaking investigation takes him from Mongolia to Canada and Patagonia in search of new evidence. He is looking for one dinosaur in particular, the ‘Tarbosaurus bataar’ which he believes will lead him to prove that the world's first pack hunters existed millions of years ago, but he also stumbles upon the many new truths behind these mythical animals.‘Dino Gangs’ contains their exclusive, groundbreaking scientific research that has finally resolved the extraordinary biology of these awe-inspiring creatures.
