Welcome to the Cretaceous! It's a wild and dangerous place but it's too awesome to resist! So Jamie and Tom set off to the Cretaceous again by stepping in the fossilized footprints in their secret smugglers' cave. They decide to try some crabbing and manage to catch a real-life prehistoric crab. But as the boys inspect the amazing creature a sneaky velociraptor runs up and grabs the Fossil Finder. Disaster! The boys have to get it back - if they don't, then future scientists might find a fossilized Fossil Finder and that could mess up the whole of dinosaur science! The chase is underway - through a valley of geysers spurting boiling water - and on to the velociraptor's lair ...This is the fifth 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.
