DESC: Fans of the renowned pop-up duo Robert Sabuda and Matthew Reinhart will find not only a gigantic prehistoric scorpion (the seven-foot-long pterygotus) leaping out at them, but also a shark, the "bus-size" whale-hunting megladon, and a crowd of fearsome long-necked sea lizards (plesiosaurs). This incredible, ocean-oriented companion to their bestselling ENCYCLOPEDIA PREHISTORICA DINOSAURS houses scads of terrific pop-ups exploring the world of the dinosaurs' underwater counterparts.

With information and pop-ups tucked in everywhere, there's sure to be something captivating for everyone from prehistoric-everything enthusiasts to miniature scientists-to-be.
