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.
