Welcome to the Cretaceous! It's usually full of the sounds of dinosaurs roaring and insects buzzing, but when Jamie and Tom visit their secret prehistoric world, they find it strangely quiet. Where are all the dinosaurs? Then they hear an explosion above them and see meteors hurtling towards Earth! As the huge boulders of space rock crash all around them, the boys are knocked off their feet. Pockets of smoke and fire appear in the trees and the dinosaurs begin to emerge from the forest. But a herd of elusive edmontosaurs are completely freaked out and begin to stampede - straight for an enormous meteor crater! If the boys can't stop them, they'll all fall to their deaths! This is the sixth 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.
