Although extinct for more than 65 million years, dinosaurs still capture our imagination today. Piecing together their legacy bone by bone, paleontologists are constantly unearthing new and fascinating facts about the emergence, life and eventual disappearance of the ancient beasts. This has caused a change in the perception of the prehistoric creatures in the last few decades ? no longer are they viewed as slow, lumbering giants, but rather active, intelligent, diverse and highly successful creatures. This book takes a look at the wast amounts of knowledge scientists have assembled by investigating the clues left by dinosaurs.
