Gaps in the genetic code have been filled in with 'compatible' reptilian, avian, or amphibian DNA, and all dinosaurs have been engineered to be female in order to prevent unauthorized breeding. Construction is nearly complete, and the dinosaurs have been recreated using fragments of ancient DNA found in the blood inside prehistoric haematophagic arthropods preserved in ambers. The 'preserve' is a cover for the construction of Jurassic Park, a theme park that will showcase living dinosaurs to the public.

Paleontologist Alan Grant and his paleobotanist graduate student Ellie Sattler are contacted to confirm the animal's identity, but are abruptly whisked away by billionaire John Hammond - founder of bioengineering firm InGen - for a weekend visit to a 'biological preserve' he has established on Isla Nublar. One of the species behind the attacks is believed to be Procompsognathus, an extinct species of dinosaur. In 1989, a series of strange animal attacks occur throughout Costa Rica and on the nearby island of Isla Nublar. The film was a critical and commercial success, becoming the highest-grossing film ever at the time and spawning five sequels. Jurassic Park received a 1993 film adaptation of the same name directed by Steven Spielberg. In 1997, both novels were republished as a single book titled Michael Crichton's Jurassic World. A sequel titled The Lost World, also written by Crichton, was published in 1995. A cautionary tale about genetic engineering, it presents the collapse of a zoological park showcasing genetically recreated dinosaurs to illustrate the mathematical concept of chaos theory and its real world implications. Jurassic Park is a 1990 science fiction action novel written by Michael Crichton.
