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 do is face all the prehistoric wonders, dangers, and terrors of the Lost World.
