The three-color lens trick is genius—slide it across the page and the whole landscape shifts from one era to another. My kid's been going back to the same spread for days, hunting for new creatures each time. It's the kind of book that makes you feel like you're on a real dig.

My nephew tore through the book in one sitting, absolutely mesmerized by the three-colour lens revealing different layers of hidden dinosaurs and plants. The detail in each prehistoric landscape is incredible, and it kept him entertained for hours without a screen in sight.

I was skeptical about a book with a viewing lens, but my kids are obsessed with seeing the hidden dinosaurs appear layer by layer. The three-color filter really makes the prehistoric scenes pop.
