The Lost World is released in 1912 by Arthur Conan Doyle concerning an expedition to the plateau in South America where prehistoric animals (dinosaurs and other extinct creatures) still survive. The character of Professor Challenger was introduced in this book. Interestingly, for a seminal work of dinosaur-related fiction, the animals only occupy a small portion of the narrative. Much more time is devoted to a war between early human hominids and a vicious tribe of ape-like creatures.
