Season 1, Episode 25 The Lost World: Venezuela's Ancient Tepuis

First Aired: September 14, 2003

British biologist and explorer Adrian Warren (who also produced) ventures into Venezuela's cloud-enshrouded mountainous plateaus known as tepuis. It's “a landscape lost in time,” says narrator Richard Doyle, and, as it happens, it's the setting of Arthur Conan Doyle's novel “The Lost World,” which (as is seen in clips from a silent-movie version) imagines an untouched place where dinosaurs roam. Warren doesn't encounter any dinosaurs, but he does find a tiny frog whose ancestors predated them, as well as Angel Falls (the world's highest, at 3212 feet), carniverous plants and surreal rock formations that “seemingly defy every law of gravity.”
