The Lost Worlds subgenre of science fiction are those works that pertain to the discovery of lost civilizations or lost worlds. The genre grows directly out of the adventure story Lost World genre antecedents popular just before World War I, such as H. Rider Haggard's works and Edgar Rice Burrough's Tarzan and John Carter series. However, to cross the line into the science fiction genre, the story must at minimum take place in a projected future or make use of technology (usually to reach the lost world) not available to our civilization.
The quintessential example of this genre of fiction is most of Anne McCaffrey's work, particularly her meticulously envisioned Dragonrider series, which takes place on a planet known as Pern, which was colonized but then largely forgotten by a future Earth. McCaffrey's series centers on this lost world's struggles to survive a menace that visits them for fifty years of every 250, and the society that evolved to confront the challenge.
