Dinosaurs just keep coming back to life! Michael Crichton, author of Jurassic Park, has written a sequel called The Lost World, which hits bookstores this week. The book stars the Jurassic Park scientists, seven-foot-tall chameleons and bad guys who wind up as dinosaur snacks. Sound like a good movie? Steven Spielberg thinks so too: he bought the rights to make the film before the book was even printed.
