Jamie has just moved to Ammonite Bay, a stretch of coastline famed for its fossils. Lots of dinosaur fans visit Ammonite Bay to search for fossils, and Jamie is one of the biggest dinosaur fans ever. He's a member of the Dinosaur Club--a network of kids around the world who share dinosaur knowledge. They help each other identify fossils, post new dino discoveries, and talk about all things prehistoric. Jamie takes his tablet everywhere, just in case he needs to contact the Club.

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 around, including her favorite place--a secret cave with fossils all over the walls. But what's that strange tunnel at the back? Together 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--and they'll definitely need help from the Dinosaur Club...

In this adventure, Jamie and Tess learn not to judge a book by its cover when they meet a group of Compsognathus. Although they look cute, they turn out to be angry little predators. The chase is on!
