Do Dinosaurs Still Exist?

The idea of still-living dinosaurs has captured the public imagination for well over a century.

Arthur Conan Doyle, creator of Sherlock Holmes, published a 1912 novel called "The Lost World," set in the remote Venezuelan jungle where dinosaurs still survive in modern times.

Films such as "Jurassic Park" and "Land of the Lost," which opens Friday, were inspired by Conan Doyle's vision — in fact, the sequel to "Jurassic Park" was titled "The Lost World."

The animated film "Up" (currently No. 1 at the box office) also takes place in this lost world, the plot involving the discovery of an unknown, multicolored dinosaur.

For most of us, fiction is good enough. Yet some believe that giant dinosaurs still exist today, just beyond the reach of scientific proof.
