Explore the next frontier of dinosaur discovery.
Canada is one of the best places in the world to study dinosaurs, with bone beds coast to coast and dinosaur tracks dating back 250 million years. Canadian Dinosaurs is the first significant book on Canadian Dinosaurs for young readers.
New technology, such as CAT scans, has helped scientists make new discoveries and rethink old ones. Dinosaur research is full of new and changing ideas -- hear about exciting questions that dinosaur experts are debating.
Canadian Dinosaurs also delves into the history of dinosaur exploration. During the Dinosaur Rush at the beginning of the 20th century, paleontologists scrambled to find fossils in the Badlands of Alberta -- each hoping to claim new species for their own museums. Old techniques are contrasted with the cutting-edge research -- surprisingly, some things haven't changed at all! Whether with horse carts or helicopters, bone excavation is still a painstakingly slow process.
Amazing photographs and detailed sketches complement Elin Kelsey's up-to-the-minute research. This book will appeal to young readers, librarians, teachers, and parents alike.
