Books in the Fantasy Field Trips series take the reader on field trips to the most unlikely of destinations! In this book, climb aboard the time machine as we prepare to travel back in time to the era of the dinosaurs. Our 'tour' includes visits to the Triassic, Jurassic and Cretaceous Periods, and takes in dinosaurs such as Tyrannosaurus rex, Allosaurus, and Plateosaurus along the way.
