This fully revised edition of Knowledge Encyclopedia: Dinosaur! is loaded with more than 60 prehistoric creatures, from the age of dinosaurs to the Ice Age. Did you know that Velociraptor had three large "killer claws" on each foot to hunt down prey? Or that the long-necked Diplodocus was as long as three school buses? Can you imagine what a strange life it would be for Saltasaurus with no toes on their front feet? Would you believe that Carcharodon megalodon was an ocean monster with a fearsome bite at least six times stronger than today's great white shark?
