Get the deets on dinos and find out how we know what we know about them, from the hosts of the popular podcast I Know Dino! Dinosaurs have been extinct for millions of years, but the world of dinosaur science has never been more alive! Over the last few decades, amazing scientific discoveries have transformed what we know about dinosaurs. And it turns out that a lot of what we thought we knew about them was ... totally wrong. Fortunately, prehistory pros and podcast hosts Sabrina Ricci and Garret Kruger are here to parse dino-fact from dino-fiction and examine the incredible history of paleontology along the way. Did you know scientists once thought Brachiosaurus could walk to the bottom of a lake and breathe through nostrils on top of its head? (False.) They also believed that Stegosaurus's back plates lay flat on its body like a turtle shell! (They didn't.) In this book, you'll find fact-packed profiles of your favorite dinosaur species. You'll learn scientists' (often wrong!) first impressions of them, and then find out how new discoveries changed our understanding. Each profile is full of incredible dino illustrations, including sketches of what we used to think each species looked like. Sprinkled throughout the dinosaur profiles, readers will also find features and sidebars all about dinosaur mysteries, battles between paleontologists, movie dinosaurs, and more! Science is alive and constantly changing, and this fascinating, colorful guide to the evolution of dinosaur knowledge shows us that there's always more to learn!
