Jamie and Tom have decided to do some prehistoric birdwatching, so they're off to their secret Jurassic world once again.

They climb up a tree to get a better look at the flying creatures of the Jurassic, but nearly fall out in surprise when a huge head appears between the branches.

It's an enormous diplodocus munching on the leaves and branches.

The boys are enjoying a close-up view of this Jurassic giant when suddenly it begins freaking out!

If this dino doesn't stop thrashing around the trees, the boys are going to fall - there's only one thing for it, they'll have to cling on to its long neck and get down that way!

This is the third of the Jurassic adventures and the ninth book in the hugely popular Dinosaur Cove series which has now sold over a million copies.

This new edition includes a set of Jurassic collector cards.
