The Lost World is a 1995 novel by Michael Crichton. It is a sequel to his earlier novel Jurassic Park. A paperback edition was issued in New York by Ballantine Books in 1996 with ISBN 034540288X. The book was later made in to a 1997 film, , which is considerably different than the movie it inspired.
Like Arthur Conan Doyle's novel of the same name, Crichton's novel concerns an expedition to an isolated Central American location where dinosaurs roam - though in this case, the dinosaurs were recreated by genetic engineering, rather than surviving from antiquity.
The eccentric mathematician Ian Malcolm and the egocentric paleontologist Richard Levine head to Isla Soma to invesigate extinction theories in the "Lost World" left by InGen's cloning program. They are joined by material engineer "Doc" Thorne, Thorne's chief mechanic Eddie Carr, field biologist Sarah Harding, and two stowaway kids: Arby and Kelly. Also on the island is the antagonist Lew Dodgeson and his two henchman.
As with the first book, the characters have to fend off attacks from T-Rexes and raptors, as well as carnotauri. Between the action scenes Malcolm and Levine talk about various evolutionary and extinction theories, as well as the nature of modern science and the homogenizing and destructive nature of humanity. Though written several years before the scares over Mad Cow Disease, the book discusses the role of prions in brain diseases.
Unlike the movie, there are no T-Rexes attacking San Diego.
