Plutonia (novel)

Plutonia is a novel released in 1915 by Vladimir Obruchev. Is a hollow-earth-type of science fiction novel set in an underground world of rivers, lakes, volcanoes, and strange vegetation, a world which has its own sun –Pluto– and inhabited by monstrous animals and primitive people. The author uses the plot for the purpose of introducing the reader to the animal and plant life of ancient geological periods in their natural surroundings. In Plutonia, dinosaurs and other Jurassic species are found in a fictional underground area north of Alaska. The descriptive passages are made more credible by Obruchev's extensive knowledge of paleontology.
