A witty set of comparisons that places ancient dinosaurs side by side with modern-day objects. Dinosaurs were gigantic beasts that walked on Earth long before humans appeared. Everybody knows the dinosaurs were BIG, but how big is BIG? As big as a fire engine? As small as a chicken? Patrick O"Brien"s marvelous illustrations place dinosaurs side by side with modern-day animals, vehicles, and people so that children can easily grasp how the dinosaurs would stack up if they were around today.
