Did you know that the big, bony back and tail spikes help to protect the Stegosaurus mother and baby from other dinosaurs? Or that a Maiasaura lays up to 40 eggs at one time! And I bet you didn't know that a baby Triceratops is born with a straight horn and as they grow it curves backwards. These are just a few of the fun things you'll learn in Baby Dinosaurs . This beautifully illustrated children's book features 10 pop-up baby dinosaurs such as the Tyrannosaurus Rex, Hadrosaur, Triceratops, and Maiasaura, along with fun facts for each.
