In this exciting sequel to , twelve-year-old Daniel Bringham travels back millions of years to the time of dinosaurs - a terrifying journey from which he may never return.
In , Daniel and Pederson, a reclusive palaeontologist living on a neighbouring farm in southwestern Saskatchewan, made a brilliant discovery - the fossil remains of a dinosaur called an Edmontosaurus.
Now, local bullies Todd and Craig Nelwin, jealous of all the attention Daniel gets, want to find his hideout and wreck it. When the three scuffle and Daniel hits his head on the rocks, he is whisked out of his own time and into the world of the dinosaurs - Triceratops, Brontosaurus, Tyrannosaurus Rex; a world of giant redwoods, huge ferns, and dragonflies nearly a metre wide. When another equally strange shock brings him back to his own time, Daniel at first doesn't realize that he carries a small piece of the past - a bit of redwood bark. Whenever he touches it, he will return to the dinosaurs' world.
Daniel makes two more unplanned but thrilling trips to the past. He sees the most marvellous, and horrifying, sights and makes new discoveries about dinosaurs. On the final trip, Daniel has two unwilling "hitchhikers" with him - the Nelwins. Daniel isn't the only one who learns from their sudden shared adventure.
A glossary of names and technical terms and a book list kids can use to expand their knowledge of dinosaurs is included.
