At a little home desk, untangling an impossible knot of phone-charging cables with its distinctive thumb spike, visibly resigned. The real Iguanodon (say it ig-WAH-noh-don) lived in the Early Cretaceous — the second dinosaur ever named; its thumb spike was first reconstructed as a nose horn. From the Storybook collection, where picture-book warmth meets real anatomy; teachers and parents of dinosaur experts, this is your series. Waterproof matte vinyl, printed when you order it and cut to the outline with a clean white border.
