Wikijunior books welcomes you to the Wikijunior book “Dinosaurs”. Dinosaurs were the biggest animals ever to walk this Earth, and their stories excite the imagination of kids of all ages. Dinosaurs have long been extinct, but the creativity of a child is so great that it can be benefited even by learning of a creature that walked the Earth millions of years ago. The importance of this task has led many experts here at Wikibooks to donate their time and talents to bring this volume together.

Wikibooks is a project of the Wikimedia Foundation, aimed at providing free, easily available quality reading for both children and adults to promote the global spread of knowledge. Traditional publishing houses make the bulk of their income from re-issues of classic books, new books by authors with long track records, or celebrities who are famous in their own right. Within Wikibooks, the research is new, the facts gathered by thousands of tireless volunteers who work without pay, without compensation, and without the urging of others. The works you see here are a labor of love on the part of the contributors and their only wish is that their knowledge be shared with the world freely.

With this project we have reached a crossroad between the books of yesterday, and the encyclopedia of everything for tomorrow. Simply by reading this book and telling your friends, you have advanced the cause of free access to information and of democratizing the field of publishing. Thank you for the opportunity; in return, our gift to you is to learn the tale of the greatest creatures that ever lived. Everyone who contributed to this book hopes that you find adventure in this book, adventure and knowledge.

This book will give you a basic understanding of dinosaurs and some of the events that happened in their time. Of all the creatures that have walked this Earth, few have captured our imagination and fed our desire for knowledge like the dinosaurs have.

One Day Millions Of Years Ago[edit]

One day, you are walking through a prehistoric forest, you hear a twig snap behind you. You turn, slowly, hoping that it isn’t what you think it is. Standing behind you is a Stegosaurus, chomping away on some leafy ferns. You breathe a sigh of relief. You were afraid it was a predator with its eye on you as a tasty snack. Of course, that was millions of years ago, so it could only happen in your imagination. In fact it was so long ago that there were no people around at all; there weren't even any apes or monkeys yet!

The prehistoric world of the dinosaurs is both strange and exciting. Many things were very different from what you see today. Some dinosaurs stood taller than buildings, and others weighed as much as your entire family put together. Some dinosaurs were small enough to fit in your backpack. Some would not hesitate to eat you on the spot if they were hungry. Others spent all day chomping on ferns and other plants. The one kind of dinosaur that never existed was a dull dinosaur!

There is so much to know about dinosaurs. What is a dinosaur? How is it different from animals today? Are there any dinosaurs living now? Where did dinosaurs live? What did they eat? What did they look like? Why are they gone? How do we know about dinosaurs? Were other animals living at the time of the dinosaurs? How did dinosaurs get their food? Did dinosaurs sleep? How did dinosaurs move? How did dinosaurs protect themselves? Did dinosaurs fight? Could dinosaurs swim? How big was a baby dinosaur? Were dinosaurs poisonous? No matter how long this book is, it could never cover everything there is to know about every dinosaur. If you wish to learn more about dinosaurs, you can find lots of information at the library. You can check out the reference section in the back of the book. You can also visit natural history museums.
