In a rip-roaring journey of peril and adventure, four explorers find a
lost prehistoric world in the remote wilds of South America. Huge
pterodactyls rule the skies and the jungle beneath is home to lumbering
stegosaurus, carnivorous dinosaurs, and terrifying ape-men. If the
adventurers can survive, then fame and fortune almost certainly await
them back in London--but in this dangerous land that defies all science
and reason, who knows what could happen?
