The Lost World by Arthur Conan Doyle
The Lost World is a novel released in 1912 by Arthur Conan Doyle concerning an expedition to a 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.
