A band of four amusing and inseparable dino-buddies awaits younger readers to guide them in the exploration of the prehistoric world. Dattila, a baby pterodactyl who is afraid of flying, but finally discovers that soaring through the skies is great fun. Trix, a small triceratops who runs away when she meets a tiny ladybird, finds that they can make friends. Bronto, a mini Brontosaurus who is still too small to be alone, without the protection of his huge father. Rex is a T-Rex in miniature who does not clean his teeth; he receives a very useful toothbrush as a gift. Four dinosaurs become cute and friendly in the illustrations of Marisa Vestita; four friends who will help children face the "small-big" problems of growing up.
