Jamie is exploring Ammonite Bay when he meets Tess. Tess is a member of Dinosaur Club who lives in Ammonite Bay too. She shows Jamie a secret cave with fossils all over the walls. But what’s that strange tunnel at the back? They go through the tunnel and they discover some dinosaur footprints. Jamie and Tess walk along them…and the two new friends find themselves back in the time of the dinosaurs! It’s amazing, but dangerous too – they’ll definitely need help from Dinosaur Club… The second four books in the series are included in this collection: The Compsognathus Chase, Catching the Velociraptor, Escaping the Liopleurodon, and Avoiding the Allosaurus. Along the way, Jamie and Tess encounter all kinds of amazing dinosaurs. At the end of each book is a reference section with a summary of all the facts and discoveries made throughout the story.
