I’m Sure I Saw a Dinosaur is a highly imaginative and slightly mischievous picture book that blends the everyday with prehistoric fantasy. The story is told from the perspective of a child who is convinced they saw a dinosaur—perhaps in the garden, at the playground, or hiding behind the sofa—despite the skeptical, rational commentary of an adult. The conflict between the child’s vibrant imagination and the adult’s reality creates humour and wonder. Jeanne Willis captures the incredible power of a child’s mind to transform the ordinary into the extraordinary. The book serves as a charming celebration of fantasy, encouraging readers to trust their imaginations and keep an eye out for the magic that might be lurking just out of sight.
