Jurassic Park is a 1990 science fiction novel by Michael Crichton. It was made into a movie in 1993 directed by Steven Spielberg.
As a story, Jurassic Park is a "going back in time" story, without actually going back in time. It's impossible, but like H.G. Wells's many books, or Conan Doyle's The Lost World, it is futurist but imaginary.
