"Sir Arthur Conan Doyle's fantastic novel "The Lost World" deals with the myth that there still exists in this world a plateau somewhere in the unexplored wilds of South America, upon which the animals of prehistoric times still live. Animals which as far as science could discover, had passed from this world some 10.000.000 years ago.
