Welcome to the Cretaceous!It's a pretty cool place, in a prehistoric hot and humid kind of way!

Jamie and Tom have followed the fossilized footprints and discovered a secret dinosaur world.

There's so much to see and do in the Cretaceous, and with their little dinosaur friend, Wanna, the boys set off to explore.

But they're stopped in their tracks when they find a baby ankylosaurus stuck in the mud.

It looks like it's about to go under and the boys know they can't just leave it.

But how do you pull a dinosaur out of amuddy swamp? Especially when the baby's mother has just arrived and is not too happy to see the boys!This is the third 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.
