Fifty years after Professor Challenger's discovery of the Lost World, America's last dinosaur circus has gone bankrupt, leaving a dozen avisaurs, centrosaurs, ankylosaurs, and one large raptor abandoned. Now a daring expedition plans to do the impossible: return the Jurassic giants to the wild. Two filmmakers, a circus trainer, a journalist, and a young Peter Belzoni must find a way to take the dinosaurs across oceans, continents, rivers, jungles, up a mountain that has been isolated for 70,000 years.... Then if they make it, all they'll have to do is face all the prehistoric wonders, dangers, and terrors of the Lost World.
