Can you imagine a world in which palm trees grew in Alaska and there were coral reefs in the mountains of Canada? Well, the world of the dinosaurs was much warmer than it is today and the climate suited them perfectly. Many different types of dinosaurs lived together, from the Brachiosaurus (as tall as a four-story building and heavier than ten adult elephants) to dinosaurs no bigger than a chicken. Some of these were ferocious meat-eaters and some were gentle giants that ate only plants. Over millions of years the landscape changed and so did the creatures that roamed the land. And then, the dinosaurs died out! What happened to them? Do you have any theories? But what if there was still one left alive and you were lucky enough to keep a baby dinosaur as a pet?

Why are people afraid of sharks? Most sharks are not interested in harming us, and there are only a few species that have ever attacked humans. This book looks at why sharks have this effect on us, and explains why we should protect and care for all sharks. The beautiful full-color illustrations showcase many fascinating sharks, from the spectacular whale shark (the biggest shark in the world) to the tiny pygmy shark, and the colorful and odd-looking woebegone to the mighty mouthed megamouth and the scary-looking great white shark. You'll find out about shark relatives such as stingrays and chimaeras and see the amazing things found in sharks' stomachs. And, as if this wasn't enough, this book gives you handy hints on how to keep a great white shark as a pet!

Deep canyons, grassy plains, high mountains, lonely deserts, beautiful beaches and other miracles of nature are all a part of North America.

Besides the user-friendly maps that let you know exactly where everything is, you'll find each country's colorful flag displayed. And look out for the page of removable stickers in the center and the interesting activity, useful glossary and index at the end.
