Arthur Conan Doyle populated the tepui Roraima with dinosaurs, strange vegetation and animals in his book, The Lost World, based on the accounts of British explorers Everard IM Thum and Harry Perkins who were the first Europeans to ascend Mount Roraima in 1884.

Subsequent explorations and modern day climbers and trekkers find no dinosaurs, fossils or traces of prehistoric life on the top of the tepui, but they do find a fantastic world of cystal valleys, gorges, sandy beaches, mists and fog, fissures, rock formations, pools and waterfalls. Mount Roraima is the tallest of the table mountains called tepuis and is located in the southeastern corner of Canaima National Park, near the borders of Brazil and Guyana.
