The Lost World
Professor George Edward Challenger is sure that dinosaurs still roam the earth and he is willing to prove it - if only he can find them in the heart of the jungle without getting attacked by natives. Accompanied by Edward Malone (who is there to jot down Challengers every word) and several faithful and trusty servants, they go exploring deep into the heart of the South American jungle and find not only dinosaurs but many other unusual and dangerous creatures.
