Welcome to the Cretaceous! It's full of the coolest creatures that ever walked the Earth! And Jamie and Tom have found a secret gateway that will take them there for adventures whenever they want. Today the boys and their wannanosaurus pal, Wanna, are on the hunt for a quetzalcoatlus - one of the biggest flying reptiles ever. It's not long before they spot the creatures gliding through the air and as one swoops down, the boys are amazed at how huge it is. But when it picks up Wanna and flies away with him, it's time for the boys to launch a rescue mission and find their little friend. This is the fourth book in the hugely popular Dinosaur Cove series which has now sold over a million copies. This new edition includes a set of Cretaceous collector cards.
