Think again! New York Times bestselling and award-winning author Steve Brusatte brings young scientists and readers everywhere into his world of massive herbivores and fearsome predators, daily unexpected discoveries, and all the new science used to learn about some of the world’s oldest beings. Even though the dinosaurs roamed the earth millions of years ago, we’re still piecing together new information about these ancient animals. Did you know that, on average, a new species of dinosaur is discovered every single week? Or that many dinosaurs had feathers? Or that there are even modern-day dinosaurs walking around right now ? New York Times bestselling author and acclaimed paleontologist Steve Brusatte writes about all the new discoveries he and his colleagues have made that help us better understand—and marvel at—these remarkable reptiles. This exciting nonfiction book for ages 7 to 12 includes a glossary, pronunciation guide, and index, as well as photos throughout. A strong choice for the classroom and for independent reading, and a great source for reports using information direct from an expert in the field.","forthcoming":false,"isbn13":"9780062930187","publication_date":"20220301","publisher":"HarperCollins","slug":"the-age-of-dinosaurs-the-rise-and-fall-of-the-world-s-most-remarkable-animals","subtitle":"","title":"The Age of Dinosaurs: the Rise and Fall of the World’s Most Remarkable Animals"},"discovery":{"categories":{"all":[{"bisac_code":"JNF025150","confidence_band":"medium","label":"Prehistoric Times","score":0.8894,"source":"bisac_hint_model"},{"bisac_code":"JNF003050","confidence_band":"medium","label":"Dinosaurs & Prehistory","score":0.8793,"source":"bisac_hint_model"},{"bisac_code":"JNF037050","confidence_band":"high","label":"Fossils & Dinosaurs","score":0.8773,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JNF025150","confidence_band":"medium","label":"Prehistoric Times","score":0.8894,"source":"bisac_hint_model"},{"bisac_code":"JNF003050","confidence_band":"medium","label":"Dinosaurs & Prehistory","score":0.8793,"source":"bisac_hint_model"},{"bisac_code":"JNF037050","confidence_band":"high","label":"Fossils & Dinosaurs","score":0.8773,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JNF003050","confidence_band":"high","label":"Dinosaurs & Prehistory","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF003330","confidence_band":"high","label":"Baby Animals","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF017000","confidence_band":"high","label":"Kids' Drama & Plays","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF025020","confidence_band":"high","label":"Ancient History for Kids","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF025150","confidence_band":"high","label":"Prehistoric Times","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF035000","confidence_band":"high","label":"Math","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF037050","confidence_band":"high","label":"Fossils & Dinosaurs","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF051000","confidence_band":"high","label":"Science & Nature","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Prehistoric Times","score":0.8894,"slug":"prehistoric-times"},{"label":"Dinosaurs & Prehistory","score":0.8793,"slug":"dinosaurs-prehistory"},{"label":"Fossils & Dinosaurs","score":0.8773,"slug":"fossils-dinosaurs"}],"reader_fit":["Readers ages 7–12 interested in dinosaurs and new discoveries","Students seeking dinosaur facts for classroom reading or reports"],"related_lists":[],"series":null,"similar_books":[{"authors":["Rachel Ignotofsky"],"book_id":"9781984861757","cover_image_url":"https://img.bookfrontier.com/9781984861757.jpg?v=6ab5638079f772ad","score":0.8514,"title":"Dinosaurs","url":"https://bookfrontier.com/books/9781984861757"},{"authors":["Professor Anusuya Chinsamy-Turan"],"book_id":"9780744039436","cover_image_url":"https://img.bookfrontier.com/9780744039436.jpg?v=0157f19b61f99c58","score":0.8301,"title":"Dinosaurs and Other Prehistoric Life","url":"https://bookfrontier.com/books/9780744039436"},{"authors":["Byron Barton"],"book_id":"9780694006250","cover_image_url":"https://img.bookfrontier.com/9780694006250.jpg?v=683b3f02b01e4f1c","score":0.8157,"title":"Dinosaurs, Dinosaurs Board Book","url":"https://bookfrontier.com/books/9780694006250"},{"authors":["Michael K.
