The new Top Ten series presents a wide range of subjects to children in a way that plays off of their innate sense of excitement and curiosity. Do you think you can name the ten deadliest dinosaurs in history? Surely, you're imagining large carnivores, such as the T. rex. But did you know that brute force didn't always prevail? Sometimes an unsuspected secret weapon used at the right time could be more effective and destructive. So, even a peaceful herbivorous dinosaur could turn into a deadly machine! The danger level will increase as we count down from ten all the way up to terrible number one! In each book, the text builds on common knowledge to unhinge unexpected facts and amazing realities about the world around us. Ages: 6 plus
