Why were dinosaurs so successful and the dominant life-form on Earth for such a long time? How did they evolve? What did they eat? Why did they die out and what animals that exist today owe their evolution to the legacy of the dinosaurs? Archaeology and science are responsible for answering many of these questions and more in this hugely informative book. From their early evolution to eventual extinction, these books span the prehistoric era where dinosaurs ruled the world. From the biggest to the smallest, the hunting and defence strategies they use and the amazing variety of body, shapes, sizes and features that make these amazing creatures so unique to our history. Find out all about their dangerous world...if you dare! Six books in the series each focus on one particular aspect of dinosaur life and characteristics. For dino-mad kids everywhere aged 8-12.
